The ABB 1SVR405621R1000 is a pluggable interface relay designed for digital signals. It provides electrical isolation, amplification, and signal matching between controlling systems such as PLCs, PCs, or field bus systems and sensors or actuators. Unlike electronic switching devices, it does not have additional internal protective circuits, making it resistant to overloads and suitable for short current or voltage spikes.
This relay features a cadmium-free contact material and a compact design with a width of twenty-seven mm, suitable for various standard sockets. It includes a mechanical status indicator and an integrated test button.
