The Siemens 3RH2131-2LA40-1AA0 is a SIRIUS coupling relay for switching auxiliary circuits — it sits between a PLC output or pushbutton and the load, isolating the control logic from the power side.
Mechanical endurance is 30 million switching cycles typical, and the relay can switch at up to 10,000 operations per hour AC — enough for high-speed cycling in a pick-and-place or packaging line where the contactor follows a fast PLC sequence.
Depth is 73 mm, width is 45 mm, and height is 70 mm.
The relay is RoHS-compliant per the substance prohibition date of 10/01/2009.
