Solid-state Relay

The SDA is a solid-state relay for applications with a DC control signal and an AC load. It is suitable for a host of applications including industrial control systems, lighting systems, vending machines, production systems, temperature control, home appliances, medical equipment and conveying systems. Two load voltage options are available – 24 – 280 V a.c. or 48 – 480 V a.c. – and load currents up to 125 A can be supplied. Allowance is made for control voltages up to 32 V d.c. Solid-state operation means that the device produces no sparking when switching, no audible noise and high-speed reaction.
