Abstract
Apparatus and method provide a solenoid coil having a field-replaceable status indicator light, such as an LED. The status indicator light lights up when power is supplied to the solenoid coil to indicate the coil is energized and turns off when the coil is no longer energized. This allows technicians and other personnel working in hazardous environments to easily and reliably monitor the operational status of the solenoid coil. An electrical splitter adapter splits power between the solenoid coil and the status indicator light. The splitter adapter allows the status indicator light to be removed without interrupting power to the solenoid coil. Where the power is AC power, a rectifier may be provided on the splitter adapter to convert the AC power to DC power.
