Solid state relays
The RS/RM series solid state relays include an LED indicator as a standard feature and are touch safe protected with a removable clip-on IP20 compliant cover. The relays carry output ratings up to 100 amps at voltages up to 600V ac. For mounting of cables with ring terminals, all input and output terminals are self-lifting and allow secure clamping of load cables up to 5 AWG, while retaining the touch-safety feature.
