Schneider Electric SSM1A16BD Solid State Relay

Schneider Electric SSM1A16BD is a single-phase solid-state relay (photocoupled relay) in the Harmony modular relays lineup. The device provides 6 A of load current at 24–280 V AC on the load side and accepts a 4–32 V DC control signal, delivering zero-voltage switching to reduce inrush and EMI. Designed for DIN-rail mounting, it’s a 1 Form A (SPST-NO) module suitable for normally-open control of AC loads from low-voltage controllers. Typical applications include switching lighting, heaters, or small motors in industrial automation, HVAC, and panel boards. Its solid-state construction offers fast switching with no mechanical wear, and its form-factor integrates with Schneider Electric's Harmony ecosystem for scalable modular installations.
