Typical Application Use :Adjustable time delay module suitable for short Time Delay ON or OFF applications that are required to respond to the change of state of an input switch or contact. Typical applications include as an interlock with an Air Conditioning System such that the unit is disabled after a short time delay (delay off) if a balcony door or window is left opened (as detected by a suitably mounted switch) or as a fan or pump run on timer (delay off).The ACDO relays delayed operation (turning either on or off) can be set to trigger between 30 seconds to 5 minutes. The ACDO can be set to respond to an input switch changing from normally closed to an open state (to trigger the timing operation) or vice versa via a user selectable jumper. The output relay can also be set to energise (delay on) or de-energise (delay off) after the adjustable time delay has elapsed with another user selectable jumper. Three indication lamps indicate power, relay on/off status & timer elapsed. This timer is designed to respond to a constant on or off change of input state not a momentary input - Use Hevac's universal timer HUDT for applications required to respond to a momentary input ie push button or movement sensor.
