Siemens SIRIUS 3RQ3018-2AF00 230V Output Coupling Relay

Product Positioning

The 3RQ3018-2AF00 belongs to the SIRIUS 3RQ3 output coupling relay series. With a coil voltage of 230V AC/DC, it can isolate and convert control signals before outputting them to field equipment. It also uses spring-loaded terminals to speed up wiring.

Core Product Advantages and Features

230V AC/DC wide voltage input

The coil can accept 230V AC or DC power supply, and is universally compatible with 50/60Hz, adapting to different control power supply conditions.

1 set of switching contact outputs

It provides one set of switching (CO) contacts, made of AgSnO2 material, which can simultaneously obtain normally open and normally closed output signals.

6A thermocurrent

The contact thermal current is rated at 6A, which is sufficient to drive common contactors or indicator lights and other field loads.

Spring-loaded terminal quick wiring

It adopts spring-loaded (insertion-type) terminals, eliminating the need for screw fastening and significantly reducing on-site wiring and maintenance time.
