AS1 DODC Series current relay with dual output is ideal for applications where users want to monitor multiple loads simultaneously and alarm when cumulative current draws reach or exceed desired setpoints. Combining the setpoint, LED indication and output functions of multiple sensors into one space-saving package, the AS1 DODC Series allows OEMs to tailor individual trip points to specific processes and trigger independent contacts. The AS1 DODC may serve as an effective over/under current monitor by energizing alarm contacts whenever sensed current falls outside the low and high band setpoints.

AS1 Series with output bypass is a standard AS1 current switch with the additional feature of allowing a user to bypass sensor operation and force the output contacts into their energized state. This feature is beneficial whenever commissioning or servicing a system as it allows the output circuit to be tested without the sensor having to be operational. Available in -FT solid-core enclosure style only.

AS1 Series NOR-FT-GO is a specialized current relay providing an electromechanical relay contact. This output allows the sensor to control much more current than other AS1 models. This contact can control loads up to 5 amps, AC or DC. Solid-state contacts generally have a much lower capacity, making this sensor much more versatile than most self-powered models. Available in a solid core style only.

The AS1 Series Compact Case current sensing switch is an inexpensive, easy-to-use ring which slips onto a conductor to give a solid state contact for indication of current flow. Ideal for use in control panels, or wherever confirmation of current flow is desired. AS1 Series Compact Case current sensing switches are a cost-effective way to detect live conductors and see current flow to fans, heaters, pumps, lighting or other AC powered devices.

• Low Sensitivity Turn-On Point - Detect current as low as 0.5A with a single conductor pass, eliminates the need to wrap conductors multiple times to increase sensitivity
• Reliable Solid-state Output
  • No moving parts provide a nearly unlimited number of operations, and powered from the monitored circuit & Choice of Outputs
  • Normally Open or Normally Closed connection. Connect the leads 24" leads to a local controller or to a terminal block for remote operation

A compact inexpensive, easy-to-use LED ring which slips onto a conductor to give a flashing indication of current flow. Available options include models with pigtail outputs for remote LED applications.

• 5/16th inch ID suitable for conductors up to 100A
• Low sensitivity turn-on point detects current as low as 0.5A with a single conductor pass
• High visibility flashing LED gives visual status
• Compact 1" package with cable tie for secure mounting

AS3 Series Current Operated Switches provide the same dependable indication of status offered by the AS1, but with the added benefit of increased setpoint accuracy. A choice of three, jumper-selectable input ranges allows the AS3 to be tailored to an application, providing more precise control through improved setpoint resolution. Self-powering, isolated solid-state outputs, 1-6A, 6-40A and 40-200A input ranges, and a choice of split- or solid-core enclosures are standard.

ASX Series Current Operated Switches are high performance current-operated switches with field-adjustable time delay to help minimize nuisance trips during start-up and operation. Designed for motor status applications where setpoint accuracy and repeatability are critical, the ASX Series offers a linear setpoint characteristic and constant hysteresis. Standard features include self-powering, jumper-selectable ranges and a choice of outputs and cases.

• Motor Protection
• High Inrush or Temporary Overload Current

ASXP Series Current Operated Switches are powered versions of our popular current switches with integral time delay. A fixed two-second delay upon trip minimizes nuisance alarms during start-up and operation in motor or heater status applications. After startup a second 0-15 second delay can be set. For use with 24VAC/DC or 120VAC supplies, this high performance product offers OEM-caliber accuracy, precision tolerances, low hysteresis and low (non-sinusoidal) frequency operation. Available with status LED and solid-core enclosure as standard.

• Motor Protection
• High Inrush or Temporary Overload Current

AS0 Series Low-current Sensors are specialized current operated switches that combine an ultra-sensitive current transformer and signal conditioning electronics into a single package for sensing AC current from 3-350mA. Useful for signal or lamp status monitoring, detecting minute fault currents or fan proving, the AS0 Series features solid-state outputs and jumper-selectable ranges, which make it a versatile choice for low-current status indication applications.

• Fan Monitoring
• Fractional HP Motors
• Fault Current Sensing

ASM Series Load Monitoring Switches are designed for overload, underload or operating window applications. Upon sensing an average operating current, the ASM self-learns and establishes a limit-alarm trip point based on +/- 15% of the average expected current draw. The ASM is available in solid- or splitcore enclosure styles.

• Conveyors (-OL option)
• Electronic Proof of Flow (-UL option)
• Pump Protection (-OU option)

DS3 Series Current Operated Switches combine a Hall effect sensor, signal conditioner and a limit alarm into a single package. The DS3 Series offers three jumper-selected current input ranges and frequency response from DC to 400Hz. Available in a solid-core case with choice of relay or a universal solid-state output.
