RELECO Genaral Purpose Relays Distributors

General Purpose MR-C Series

RELECO general purpose relays are used for most general applications, such as automation, pneumatic, heating appliances, signaling, as an input or output interface, etc.

35 x 35 mm round plug-in relay, 8- or 11-terminals multipole connector according to IEC 67 with 2 or 3 contacts up to 10 A and different contact types and contact materials. Standard relay 35 x 35 mm with flat blade connectors with up to 4 contacts and up to 16 A with 3 contacts.

When the coil is disconnected from an electromagnet, peaks of inverse voltage appear at the terminals which can reach very high values. These pulses can be transmitted down the line associated with the coil and could possibly affect other components. In the case of a realy being operated by such devices as transistors, triacs, etc; it may be necessary to protect against transients.

RELECO Bifurcated Contacts Relay Low/Current Level Loads Distributor

Bifurcated Contacts

There are different contact types. The main distinction is between single contacts and twin contacts. While single contacts are more suitable for higher loads, twin contacts are significantly more reliable at small loads, i.e. < 24 V, < 100 mA.

RELECO relays with twin contacts are used to switch low currents with high operational reliability.

Twin contacts increase reliable switching by factors of 10 to 100 times. 10µ hard gold plated contacts help to avoid contact oxidation. Together this allows reliable switching of very low level signals through the contacts.

Low level voltages in analogue circuits and signal voltages <10V/5 mA are not easily able to overcome contact resistances. Twin contacts increase contact reliability and gold contacts avoid contact oxidations and are especially suitable to switch low power signal loads.

RELECO Open Contacts DC Load Switching Relays Distributors

Open Contacts DC Load Switching

An open contact arrangement allows an increase in the contact gap, increasing the DC "break capacity" without altering the AC performance.

Relays with increased contact distance of at least 3 mm allow safe separations in power circuits of high voltage currents and increase the protection degree from potentially lethal currents.

Releco offers a wide range of relay types and versions and associated sockets and accessories. Suitable sockets are available for the different relay series for DIN rail mounting or panel mounting. In addition, retaining clips are available for the relays, some of which are included in the scope of supply. Suitable bridges for cost-saving wiring in series are also available.

RELECO relays are made from high-quality, carefully selected materials. They comply with the latest environmental regulations such as RohS.

RELECO Double Make DC Load Switching Relay Distributor

Double Make DC Load Switching

RELECO double make relays are designed to switch high DC loads at voltages of 110 and 220 VDC.

Increased contact gaps, double make contacts, and arc blow-out magnets to reduce contact erosion (burn offs). Compared with standard contacts, the reliability can be remarkably increased when using customized contacts for switching DC loads with breakaway sparks. Increased contact caps, double make contacts and blow out magnets are causing a longer distance for the electric arc. Electric arcs are extinguished quickly and increase significant the lifetime of the contacts.

If consists of one normally open contact with a gap > 3 mm so that the arc length is divided by two.

Isolation between contacts is > 2000 Vrms.

X version RELECO double make relays are available in MR-C and QR-C type housing.

RELECO Latching/Remanence Relays Distributors


While "normal" relays are monostable, i.e. they return to the idle state when the excitation is switched off, remanence relays are bistable, i.e. the current switching state is retained irrespective of the excitation. Relays of this type are available in different versions.

A high remanence magnetic circuit allows the relay to latch positively when the current applied flows through the coil in a direction and delatches if the current flows in the opposite direction.

Electronic circuitry is added inside the relay to control this action and also protects against transient voltages.

There is one winding for AC coils and two windings for DC coils.

All coils withstand permanent connection. The relay can be operated with pulses of 50 ms, minimum, at nominal voltage.

RELECO Magnet Blow-Out Relay Distributor

Magnet Blow-Out

RELECO magnet blow-out relay versions are similar to X types (Double Make Relays), however they have an addition of a powerful magnet which "blows out" the arc generated when the contacts are opened, therefore quenching the arcing quickly and increasing the contact life.

They are able to switch DC loads of up to 10 A @ 222 V DC1 and 2 A @ 220 V DC13.

There is no all-purpose contact! AgNi is used as standard material for a wide range of applications. AgNi contacts with hard gold plating (up to 10 µm) are offered for applications in aggressive atmosphere. Relays with gold contacts are approved for relatively high currents (e.g. 6 A, 250 V), but in practice values of 200 mA, 30 V should not be exceeded for operation with intact gold plating.

RELECO Sensitive 500 mW - 800 mw Relays Distributors


RELECO sensitive DC relays adjusted to work at lower power, available in both MR-C and QR-C versions. Relays with sensitive coils have considerably less power consumption than standard relays. This allows up to 90% energy saving with practically identical switching capcity.

Relays with sensitive coils have improved and more effective magnetic circuits than coils of standard relays. The result is a considerably reduced coil current compared to a standard relay but with an almost identical switching capacity per contact. This means lower power consumption and therefore more economical operating and less heat. Under some circumstances, the user can provide a smaller power supply and save costs.

35 x 35 mm round plug-in relay, 8- or 11-terminals multipole connector according to IEC 67 with 2 or 3 contacts up to 10 A and different contact types and contact materials. Standard relay 35 x 35 mm with flat blade connectors with up to 4 contacts and up to 16 A with 3 contacts.

RELECO High Inrush Current Relay Distributor

Lamp Switching

The movable relay C7-W10 is ideal for industrial applications. The tungsten (W/AgSnO2) pre-contact makes it possible to handle inrush currents up to 500 A for 2.5 ms. Tungsten contacts have a higher melting point that help resist high power peaks and protect main contacts High power peaks during switch-on of electrical loads, for example when switching power supplies and ballasts can lead to welding of the contacts. Early make tungsten contacts resist high inrush currents and avoid contact welding.

Lighting technology has been changing for some years now. Traditional light bulbs are rapidly being replaced with energy-efficient light sources such as fluorescent lamps and LEDs. All of these lamps have one thing in common: they require electronic control gear (ECG). The contacts on conventional relays wear out very quickly if used for triggering these devices. Pre-devices such as relays and contactors are placed under an increased strain when switching ECGs and energy-saving lamps with integrated ECGs. This has to be taken into consideration when planning a new system.

RELECO Railway Applications Relays Distributors

Railway Applications

Relays as per Railway standard EN50155/EN60077/EN61373 are more suitable for applications with shock and vibration and have a higher degree of surge protection. Many of these railway relays also comply to additional fire protection standards, have lower inflammability and develop less toxic smoke and gases in case of fire.

Relays specially developed to comply with railway standards are designed for higher vibration, shock and surge values and allow higher tolerance in the voltage supply. Some of these relays additionally comply to special fire protection standards in regard to inflammability and the development of toxic smoke and gases in fire accidents.

Although specially designed for railway applications these relays are also suitable for other industrial applications where increased product safety is required.

RELECO Solid State Relay Distributor

Solid State

RELECO solid state relays are used to switch up to 50 VDC, heating elements electrovalves, motors, input/output signals on PLCs, solenoids, incandescent and fluorescent lamps, etc. Inductive loads must be shunted with an antiparallel diodes.

Long Life relays are relays of robust mechanical structure with 5 times longer life cycles compared to standard relays. Unlimited switching cycles are reached with solid state relays.

The Long Life Relays with a more robust design provide a 5 times longer service life. Standard relays are designed for 10 to 20 million mechanical switching cycles.

For periodical switching frequencies in the second or minute range, the standard relays reach their life cycle within a few months. The long life relays are specially designed for frequent switching applications.
