Remote Power Controller Guards PLCs Against Overloads

The E-1048-700 solid-state remote power controller (SSRPC) protects programmable logic controllers (PLCs) from overloads and short circuits. The unit helps increase current capacity and protect low-current-carrying PLC outputs. Power amplification of PLC output signals is provided without the need to change PLC output cards. Available for 24-V dc power supplies, the E-1048-700 is offered in current ratings of 0.5, 1, 2, and 4 A. The SSRPC suits dc switching resistive, inductive, and lamp loads. In the event of an overload or short circuit, the E-1048-700 power controller provides rapid current limiting followed immediately by disconnection of the load. Also, an LED indicates overloads and short circuits, wire break, and status of load circuit. Measuring just 12.5 mm wide, the unit plugs into any standard 17-P10-Si terminal block or into the company's DIN-rail-mounted 17plus Power Distribution Module. The E-1048-700 circuit breaker costs about $40 each in medium-sized production lots.
