These extremely durable smart switch modules are designed to withstand the most extreme automotive and industrial applications.  Each timer module utilizes intelligent semiconductor technology that when subjected to a short circuit, over voltage, over temperature, and/or an overload condition the output will automatically turn off.  This feature protects the module, wiring, and any components connected to the output.

Field Programmable Off-Delay Timer Module
On a field programmable Off-Delay timer module the output automatically turns "ON" when the relay is powered up and when the input 1 is in an active state. When input 1 has activated (triggered), a timing sequence will begin, keeping the output energized until the preset Off-Delay time has elapsed. This Off-Delay duration is specified when ordering and can be configured in seconds, minutes, hours, or even days. At the end of the off-delay sequence, the output de-energizes and remains de-energized until a reset is performed by removing main power from pin 4.  All 1500/1600 series field programmable off-delay timers include a secondary input for applications requiring variable timing. With each momentary ground impulse on input 2 the on-delay duration will be prolonged by the duration specified (T2).

Typical Application: Boat Shower Pump

Field programmable off-delay timer modules could be used to conserve water on marine applications.  Utilizing a simple ON/OFF switch a 12V water pump could be configured to automatically pump for 30 seconds whenever a switch is turned on.  In applications where the standard off-delay duration is inadequate an optional normally open push button switch could be installed to prolong the off-delay duration.  Each press of a momentary push button switch allows the user to easily reconfigure the off-delay duration.
