DiT Darwell Integrated Tech - HVAC Point Leak Detector - WD1 - New Old Stock

Description

DiT Darwell Integrated Technologies - Point Leak Detector
Model: WD1
New old stock surplus, Factory sealed in the original box.
The DiT, Inc. WD-1 and WD-1-S are basic point water detectors featuring silver-plated probes and microchip technology, a design that provides the highest level of water detection confidence. Power for the units may be from 12 to 24 VAC or VDC. For application flexibility, form “C” relay points are provided for connection to Darwell's GMP, MPR or similar monitoring equipment. The WD-1 and WD-1-S are each housed in a height-adjustable, galvanized steel enclosure.
The WD-1 or WD-1-S may be utilized with any “contact closure” monitoring panel or system. To accommodate virtually all installations, the “dry” contact points may be wired normally open or normally closed. Once powered, relay contacts on the WD-1 remain in the same state until water reaches the sensing probes, closing the contact. The WD-1-S sensors are reverse acting and make contact as soon as power is supplied to the unit. The presence of water releases the contact and the relay returns to a non-powered state.
