AC Mains Voltage Detector Products

Description

The AC Mains 120V/220V voltage detector can be used to detect when the power on a line from an outlet is turned on/off, such as lights, appliances, or determining when power outages occur. The detector determines if 120V/220V AC power is supplied to the input terminals and outputs a lower voltage level digital on/off signal that can be read by microcontroller, SBCSingle Board Computer, or PLCProgrammable Logic Controller. The mains AC voltage detector modules are available in single channel or multiple channels.

More details on AC Mains Voltage Detectors, including operation, pinout, schematics, and board layout, are covered in the AC Mains Voltage Detectors article.
