Product Positioning

The Siemens SIRIUS 3RH2131-2JB40 is a coupling contactor relay. It features a 24V DC coil and a cage-clamp design, providing four sets of auxiliary contacts: three normally open and one normally closed. It also has a built-in suppression diode, making it suitable as a coupling relay between a PLC and a control circuit.

Core Product Advantages and Features
3 normally open + 1 normally closed contact combination
It adopts 4 sets of auxiliary contacts, including 3 sets of normally open (NO) and 1 set of normally closed (NC), which are suitable for control circuit signal conversion, interlocking and PLC input/output interface.
Cage Clamp
Spring-loaded terminals allow for screwless, quick-connect wiring, reducing control panel wiring and maintenance time.
Signal Chain Application
It is suitable for signal interlocking, isolation and conversion in control loops, and serves as a coupling element between the PLC and the main circuit.
Integration of suppression diodes
Built-in suppression diode (0.7~1.25 times rated voltage) absorbs the induced surge voltage at the moment the coil is released.
