Schneider Electric SSM1A312BD

The Harmony SSM1A312BD solid state modular relay offers a robust solution for controlling resistive loads in single-phase circuits. This DIN rail mount relay is designed with a current rating of 12A, utilizing a DC input voltage range of 4–32V to trigger its operation. The output supports AC voltages between 48V and 600V, incorporating zero voltage switching technology for reduced harmonic distortion and improved power factor. A visual indicator provides real-time status feedback on the relay's input state. To ensure optimal thermal management and longevity, the relay incorporates a built-in heatsink. The absence of mechanical contacts contributes to silent operation and enhanced reliability. Furthermore, the clear wiring schematic printed directly on the socket facilitates straightforward installation and ongoing maintenance.
