The current being monitored can be of any voltage, up to the rating of the socket. An LED indicator is provided to show when the relay is energized.
The Model 273 is available for either 24VAC or 120VAC supply voltages. Model 273-5 is UL Recognized and CSA Certified. All versions use a standard 8-pin socket.
