Control Circuit Load
Low-power electrical load in a control, automation, or signalling circuit.
A control-circuit load is an individual consumer supplied from an auxiliary control power source or control transformer.
This category may include contactor and relay coils, solenoids, signalling devices, electronic modules, and other control consumers.
Relevant design characteristics include load type, operating voltage, power consumption, and starting or pulse-current behaviour.
The combined parameters of these loads are used to size the power supply, control transformer, conductors, and protective devices.
Control-circuit loads for relay, PLC, and machine-control systems.
