The WD100 is a microchip‑based device that uses gold‑plated sensing probes to detect the presence of water or other conductive liquid. The WD100 is powered by an AC or DC source, 14 ‑ 30 volts. It features normally open and normally closed (form C) relay contacts rated at 5A @ 120 VAC/30 VDC for connection to a monitoring system, or direct control of another device. The mounting legs will allow a sensing height adjustment from 0" to 1/2". The WD100 is designed to signal an alarm if one or more of three conditions are met: water is detected, power is lost to the unit, or if there is an internal failure. The WD100 provides the highest level of water detection confidence.
