Description
About the SSM
About the SSM
The Schneider Electric SSM1A112BD is a Harmony Solid State Relays DIN-rail mounted single-phase relay rated 12 A, switching a 24-280 V AC load with zero-voltage switching. It is controlled by a 4-32 V DC input, has a built-in heat sink, and signals input status with a green LED.

Selection Notes
The SSM1A112BD suits resistive loads up to 12 A controlled by a low-voltage 4-32 V DC signal, typically from a PLC output; choose the SSM1A112P7 instead when the control signal is a 200-265 V AC line voltage.
