Panel interface relay, 24 VAC/DC coil
The ABB 1SVR405541R3110 is a compact interface relay with a 1 CO changeover contact, designed to bridge PLC or controller outputs to higher-current field loads. The coil is rated for 24 VAC/DC, so it works on either supply without rewiring — useful in mixed-voltage panels where both AC and DC control circuits coexist. The output contact handles 6 A at 250 VAC, which covers solenoid valves, contactor coils, and indicator loads common in machine control cabinets. Screw terminals on both coil and contact sides mean no special tooling for termination — standard slotted or Phillips driver is all that's needed.
