The ENVIROMUX® AC Voltage Detector with Relay detects voltage from 50VAC to 250VAC when connected to an environmental monitoring system with dry contact inputs, battery, sensor, or other device. The internal relay closes when sensing voltage above 60VAC and opens when sensing voltage 55VAC and below.
