ВЫХОДНОЕ СОГЛАСУЮЩЕЕ УСТРОЙСТВО С ВТЫЧНЫМ РЕЛЕЙНЫМ МОДУЛЕМ 3RQ3118-2AM00

SIRUS 3RQ3 coupling relays in narrow 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 relays
• Coupling relays with semiconductor output (not plug-in)

Coupling relays with relay output (not plug-in)

AC and DC operation

IEC 60947‑5‑1, DIN 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 relays

AC and DC operation

IEC 60947‑1

These coupling relays are plug-in so that 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 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, and are therefore particularly well suited for solid-state systems.

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

Spring-type terminal with push-in functionality

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

As with other spring-type terminals, a screwdriver (with 3.0 x 0.5 mm blade) is required to disconnect the conductor. The same tool can also be used to wire fine-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.
