What is the Schneider Electric SSM1A16B7?

This modular relay belongs to the Schneider Electric's Harmony Solid State relays range. This Harmony SSM is a 1-phase relay, with zero voltage switching, ideal for resistive loads. It is rated 6A, is controlled with a 18V to 36V AC input, has a rated load voltage of 24V to 280V AC. It is silent, reliable, and has a longer operational life thanks to the absence of moving contacts. It has a visual indicator showing the status of its input, and also has a clear schematic on the side of the socket, enabling easier wiring and maintenance. The SSM relay socket connection is by screw connector type. Its dimensions are 11mm (width) x 90.3mm (height) x 83.7mm (depth) and weighs 0.05 Kg. It comes with IP20 degree of protection. Its design fits industrial machines, packaging, textiles, HVAC, automation control panels, low/medium voltage switchgear, motor controls, PLC Interfaces, power supplies, building or medical equipment, and lighting controls. Product that conforms to IEC 61000, IEC 60950-1, and IEC 62314 standards and certifications like CE, UL, CSA, ROHS and REACH. The SSM comes with a built-in heatsink for maximum performance and fewer spare parts to manage. It is designed for symmetrical DIN rail mounting. Solid State relays are silent and reliable thanks to the absence of moving contacts which in turn provides longer operational lifecycle.
