Schneider Electric SSM1D26BD Solid State Relay

The Schneider Electric SSM1D26BD is a single-phase Harmony Solid State Modular Relay designed for DIN-rail mounting in industrial control panels. This SPST-NO (1 Form A) module switches DC loads up to 60 VDC at up to 6 A and accepts a DC control signal in the 4–32 V range, enabling direct interfacing with PLCs and automation controllers. As a photo-coupled solid-state relay, it provides galvanic isolation between the control input and the load output and is intended for DC switching of loads such as DC motors, solenoids, and other low-voltage DC devices. Part of Schneider Electric's Harmony family, the SSM1D26BD combines compact DIN-rail form factor with robust switching performance, making it suitable for panel-mounted control circuits where quick, reliable DC load control is required. The device's load-side ratings of 1–60 VDC and 6 A, along with DIN rail mounting, support streamlined integration in compact automation architectures and industrial equipment where solid-state reliability and long life are advantageous over electromechanical relays.
