6 second to 20 minute 12Vdc timer board with choice of either "instant-on delayed off" or "delayed-on and hold" operation with a relay output (C, NO, NC). Countdown starts when power is applied to the board. The relay changes state at the end of the user set delay period and remains in that condition until the power is removed.
An on-board jumper selects the operation mode.
The delay time is quick and easy to set using a series of on-board jumpers and a trimpot. The number of "counts" made is set using a bank of nine possible jumper positions (8, 16, 32, 64, 128, .... to 8192). A trimpot allows you to set the time period for each "count".
Timing range as supplied is from about 6 seconds to a maximum of two hours. Up to 22.7 hours is possible using different components for the RC network (not provided).Specifications
