Siemens 3RQ3018-2AB00 Output Coupler Relay
Siemens 3RQ3018-2AB00 output coupler relay, 1 C/O contact.
The Siemens 3RQ3018-2AB00 is an output coupler relay, now a phased-out product with the preferred successor being the 3RQ4018-2AB00. This relay features one change-over (SPDT) contact and operates on a 24V AC/DC power supply. It has a narrow width of 6.2 mm and utilizes spring-loaded (push-in) terminals for easy connection. The thermal current rating is 6 A.
This type of output coupler relay is used to interface between different voltage levels or signal types in control circuits, often to isolate control signals from higher power loads or to provide additional contacts. It is commonly found in industrial control panels, automation systems, and machinery where signal isolation or expansion is needed.
