SIRUS 3RQ3 coupling relays in slim design are used to connect control signals from and to a PLC, and they are available in different versions:

• Coupling relays with relay output (not plug-in)
• Coupling relays with plug-in relay
• Coupling relays with semiconductor output (not plug-in)

Coupling relays with relay output (not plug-in)

AC and DC operation

IEC/EN 60947‑5‑1

The input and output coupling relays differ with regard to the positioning of the terminals and the LED.

Coupling relays with plug-in relay

AC and DC operation

IEC 60947‑1

The coupling relays are plug-in, so the relay can be replaced quickly at the end of its service life without detaching the wiring.

Coupling relays with semiconductor output (not plug-in)

AC and DC operation

IEC/EN 60947‑1, EN 60664‑1 and EN 50005;
Coupling relays with semiconductor output: EN 60747‑5;
programmable controllers: IEC 61131‑2

The input and output coupling relays differ with regard to the positioning of the terminals and the LEDs.

The coupling relays with semiconductor output have extremely high contact reliability, so they are especially suitable for electronic systems.

For test purposes, versions are available with manual-0-automatic switches.

Spring-type terminals (push-in) with TOP wiring

Push-in connections are a form of spring-type terminals allowing fast wiring without tools for rigid conductors or conductors equipped with end sleeves.

As with other spring-type terminals, a screwdriver (with 3.0В xВ 0.5В mm blade) is required to disconnect the conductor. The same tool can also be used to wire finely-stranded or stranded conductors with no end finishing.

The advantages of the push-in terminals are found, as with all spring-type terminals, in speed of assembly and disassembly and vibration-proof connection. There is no need for the checking and tightening required with screw terminals.

With the TOP wiring method, the wire inlet and terminals can be reached from the front. This helps to speed up the wiring process and eliminate wiring errors.
