Siemens SIRIUS 3RQ3018-2AB01 Hard Gold Contact Output Coupling Relay

Product Positioning

The 3RQ3018-2AB01 is the hard gold contact version of the SIRIUS 3RQ3 output coupling relay in the 24V specification. The contact plating reduces the contact resistance when switching small current signals, improving the reliability of low-potential signal transmission.

Core Product Advantages and Features

AgSnO2 hard gold plating contacts

The contact surface is treated with a hard gold plating, which can effectively reduce contact resistance and oxidation risk during small signal switching.

24V AC/DC coil

The coil can accept 24V AC or DC power, which conforms to the common voltage specifications of PLCs and control panels.

1 set of switching contacts, 6A thermal current

It provides one set of switching (CO) contacts with a thermal current rating of 6A, catering to both small signal and general load switching needs.

Spring-loaded terminal design

Using spring-loaded (insertion-type) terminals, wiring can be completed quickly without screws or tools.
