Would you like a single safety relay for all your safety applications? Then choose the RT6 universal relay to supervise both your safety devices and the internal safety of your machinery. In addition you can select the safety level required for each installation. All this is possible because the RT6 has the most versatile input option arrangement available on the market. The relay also comes with other options such as manual or automatic reset. Manual supervised reset can be used for gates and other safety devices that can be bypassed.

The RT6 also has information outputs that follow the inputs and outputs of the relay. These outputs will for example indicate if a gate is open or closed and if the safety relay needs to be reset. The RT6 is designed with a minimum amount of components thus keeping both production costs and component acquisitions to a minimum.

The RT7 is a universal relay that can be used to supervise both safety devices and the internal safety of your machinery. The RT7 has four (4 NO) dual safety outputs of which two may be delayed for up to three seconds in order to achieve a safe and 'soft' stop. A 'soft' stop allows machinery to brake and stop gently before power is removed. A 'soft' stop has many benefits: the machinery life will be prolonged, processed products will not be damaged, and restarts from the stopped position are made possible and easier.

Another option with the RT7 is manual or automatic resetting. A manual supervised reset is used for gates and other safety devices that can be bypassed, while an automatic reset is used for small safety hatches if deemed appropriate from a risk point of view. In addition, the RT7 has information outputs that follow the inputs and outputs of the relay.

Would you like a small safety relay for all your safety applications? Then choose the compact RT9 universal relay to supervise both your safety devices and the internal safety of your machinery. In addition, you can select the safety level that is required for each installation. All this is possible due to the RT9 offering the most versatile input option arrangement available on the market. The RT9 can therefore replace many other relays.

Other RT9 options include selection of either manual supervised or automatic resetting. The manual supervised reset can be used for gates and other safety devices that can be bypassed. Automatic reset can be used for small safety hatches, if deemed acceptable from risk assessment. In addition, the RT9 has a double information output that will indicate e.g if a gate is open or if the relay needs resetting. The RT9 uses the latest component technology and modern assembly techniques to ensure a highly cost effective solution.

The JSBRT11 has dual and monitored internal safety functions. Power failure, internal component failures or external interference (with the exception of short circuiting of input contact when used in a single channel input mode) do not result in a dangerous function. When wired for supervised reset, should a short circuit appear across the reset input the relay will not automatically reset when the input/inputs are made. Only when the supervised reset input is made and broken will the relay reset.

The JSBRT11 provides detection of contact failure in the inputs when wired in dual channel mode. Both inputs have to be opened and closed in order to enable the reactivation of the relay. The highest safety level of the JSBRT11 is in configuration mode 3 and 4 because all short circuits are supervised i.e. a short circuit between the inputs leads to a safe state as the outputs drop out.

The JSBR4 has two inputs, which both have to be closed to keep the safety output contacts closed. A short-circuit across the inputs will cause the output contacts to open. The inputs can however be subjected to a continuous short-circuit without damaging the safety relay. The JSBR4 has a twin supervised safety function. Component failure, short-circuit or external disturbance (e.g. Loss of Power Supplies) will not prevent the safe function of the relay. This is valid both for the inputs A and B as well as for the reset input. The JSBR4 operates at the highest safety level for safety relays (PL e according to EN ISO 13849-1).

The JSBR4 is designed and approved in accordance with appropriate directives and standards. The JSBR4 complies with the highest safety level for the connection of a two-hand device of type IIIc in accordance with EN 574.

The JSBT4 has two inputs, both of which have to be closed in order to keep the safety output contacts closed. A short circuit between inputs A and B will cause the output contacts to open. The inputs can be continuously short circuited without damaging the safety relay. For the outputs to close, the test input must be closed. The test input is intended to monitor that contactors or valves have dropped/returned before a new start is permitted.

This test input must not be confused with the reset function required for gates that a person can walk through and where there is a high safety requirement (see JSBR4). If the JSBT4 is used for safety Mats and safety Strips, the "stop" condition is given following detection of a short circuit. The safety mat, safety strip or the relay will not be damaged by a continuous short-circuit. This also provides the advantage that if there is a failure between inputs A and B in the installation, the safety relay will not be damaged.

The BT50 is designed to connect safety devices, such as emergency stops, directly in the voltage supply circuit to the relay. Despite a maximum built-in width of 22.5 mm the relay is very powerful. With 3NO safety outputs, 1NC output (for monitoring purposes), a test input and complete internal supervision, the BT50 is quite unique. In addition, delayed outputs (BT50T) can be ordered.

In order for the safety outputs to close, the supply voltage, e.g. by means of An Emergency Stop Button, must be connected to A1 and A2 and the test input closed. After actuation of the relay the test input can be opened again. The test input is intended to supervise that contactors or valves have dropped/returned before a new start can be permitted.The test input can also be used for starting and the start button can be supervised.

The BT51 is designed to connect safety devices, such as emergency stops, directly in the voltage supply circuit to the relay. Despite a maximum built-in width of 22.5 mm the relay is very powerful. With 4 NO safety outputs, test input and complete internal supervising, the BT51 is quite unique. In addition you can order delayed outputs (BT51T).

In order for the safety outputs to close, the supply voltage, e.g. by means of an emergency stop button, must be connected to A1 and A2 and the test input closed. After actuation of the relay the test input can be opened again. The test input is intended to supervise that contactors or valves have dropped/returned before a new start can be permitted.The test input can also be used for starting and the start button can be supervised.

The JSBT5 is designed to connect safety devices, such as emergency stops, directly in the voltage supply circuit to the relay. Despite a maximum built-in width of 22.5 mm the relay is very powerful. With 3 NO safety outputs, 1 NC, test input and complete internal supervising, the JSBT5 is quite unique. In addition you can order delayed outputs (JSBT5T).

In order for the safety outputs to close, the supply voltage, e.g. by means of an emergency stop button, must be connected to A1 and A2 and the test input closed. After actuation of the relay the test input can be opened again. The test input is intended to supervise that contactors or valves have dropped/returned before a new start can be permitted. The test input can also be used for starting and the start button can be supervised.

The JSHT1A/B closes two independent relay outputs during a guaranteed maximum time when the inputs are opened. Time reset can prevent unintentional reset of safety systems when someone is still in the dangerous area of the machine. During a guaranteed maximum time, one or several PB´s for reset must be activated. The reset buttons should be sited in such a way that operatives have a clear overview of the whole area which is guarded. Time reset is made by the combination of a safety relay and the timer relay JSHT1A/B.

The JSHT1 can also be used for time bypass of light beams for e.g. autotruck into a dangerous area. When the inputs open the output contacts close. The output contacts open when the inputs close or when the time period has expired. The time period is hardwire selectable on terminals T1, T2 and T3. The time given is the maximum time. One or two channel operation is also hardwire selectable.

The JSHT2A/B/C closes two independent relay outputs during a guaranteed maximum period of time when the inputs are closed. Sensors detect the autocarrier and are connected to the JSHT2 which supervises the sensors and bypasses the light beam for a maximum predetermined time.

Inching applications require safety outputs to be closed for a predetermined maximum period of time, allowing the machine to move only a short distance each time the inching control is activated. For each new motion the inching control e.g. PB or pedal must be released and activated again. The JSHT2A/B/C is designed and approved in accordance with appropriate directives and standards.

A safe soft stop is achieved by means of a safety relay which gives the program stop, and an expansion relay, E1T, which gives safe delayed stop signals. The drop time delay on a E1T can as standard be selected from 0 to 3 seconds. By connecting several E1T's in series even longer times can be achieved.

The E1T has twin stop functions, that is, two relays with mechanically operated contacts. A monitored stop function is achieved by connecting the test output (terminals X1 and X2) to the test or reset input on the safety relay which is being expanded. One condition for a safe delayed stop is that the delay time cannot increase in the event of a fault. The E1T complies with this requirement.

A safe soft stop is achieved by means of a safety relay which gives the program stop, and an expansion relay, JSR1T, which gives safe delayed stop signals. See section "Connection examples". The drop time delay on a JSR1T can as standard be selected from 0 to 10 seconds. By connecting several JSR1T´s in series even longer times can be achieved.

The JSR1T has twin stop functions, that is, two relays with mechanically operated contacts. A monitored stop function is achieved by connecting the test output (terminals X1 and X2) to the test or reset input on the safety relay which is being expanded. One condition for a safe delayed stop is that the delay time cannot increase in the event of a fault. The JSR1T complies with this requirement.

The JSR2A expansion relay is used to provide increased switching capacity and number of safety outputs to a safety relay. This means that an unlimited number of dangerous machine operations and functions can be stopped from one safety relay. The JSR2A Expansion relay enables switching of up to 10 amps (AC/DC) per output contact.

The JSR2A has twin stop functions, that is, two relays with mechanically positively guided contacts. A monitored stop function is achieved by connecting the test output (terminals X1 and X2) to the test or reset input on the safety relay which is to be expanded. The JSR2A is designed and approved in accordance with appropriate directives and standards.

By connecting the JSR3T expansion relay to a compatible Safety relay it is easy to obtain safe "delayed" outputs. The JSR3T provides the system designer with the facility to hardwire selected time delays in steps between 0.5 and 10 seconds. The output of the Safety relay is used to provide both a stop signal to the machine control system i.e. via a PLC which applies the necessary braking/stopping of the machine in a controlled way, and to switch a delayed expansion relay e.g JSR3T. The delayed safety outputs of the JSR3T expansion relay are then used to control the safe disconnection of the power to the actuators/motors etc. of the machine.

The JSR3T has twin stop functions, using two positively guided contact relays. In order to achieve the level of monitoring required the JSR3T must be used with a suitable Safety Relay e.g. JSBR4, or RT6. The JSR3T test output (terminals X1 and X2) must be connected to the test input of the Safety relay being expanded. The JSR3T provides delay times that even in the event of an internal fault condition complies with the requirement that the set delay cannot increase in time.
