AutomationDirect SSR210-DC10-44K Solid State Relay

The AutomationDirect AD-SSR210-DC solid-state relay is a 10 A, SPST normally open device designed to switch AC loads from a DC control signal, intended for DIN-rail mounting in control panels. The DC input accepts 3–32 VDC with a typical input current around 16 mA and a release voltage near 1 VDC, and a red LED status indicator shows when the relay is energized. The output uses a silicon-controlled-rectifier (SCR) arrangement to switch 24–280 VAC loads, providing robust dv/dt immunity and supporting a minimum load current of about 50 mA with surge capability in the tens of amperes for a single cycle. Its compact 35 mm DIN-rail footprint makes it convenient for PLC and automation applications where reliable AC load switching is required from a low-voltage control signal. Related variants exist in AutomationDirect’s AD-SSR210 family (for example 22-DCZ/ACZ configurations), and AutomationDirect lists the AD-SSR210-DC as a retired/discontinued product, so availability should be confirmed if sourcing today.
