3RH2131-1SB40
Siemens SIRIUS 3RH2131-1SB40 coupling relay, 24V DC, screw terminal, 4 sets of contacts (3NO+1NC), S00 base, suitable for control circuit signal conversion and interlocking, authorized supplier by Kenxin Motor.
Product Positioning
The Siemens SIRIUS 3RH2131-1SB40 is a coupling contactor relay with a 24V DC coil and screw terminal design. It provides four sets of auxiliary contacts: three normally open and one normally closed. It also has a built-in suppression diode to protect the PLC output contacts, making it suitable as a signal coupling relay.
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.
Screw terminal
The screw terminals provide a secure connection and are suitable for control panel wiring that requires long-term stable operation.
PLC output protection design
With a built-in suppression diode and screw terminals, it is suitable for applications requiring long-term stable PLC output signals.
Integration of suppression diodes
Built-in suppression diode (0.85~1.85 times rated voltage) suppresses the instantaneous induced surge when the coil is released, protecting the PLC output contacts.
