12Vdc Instant On or Delayed-On Timer Relay Board

AS3152KT - 12Vdc Instant On or Delayed-On Timer Relay Board
Pre-Assembled and Kit versions availableMade in Britain

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.

Setting is quick and easy. The delay time is set using 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). The trimpot allows you to tweak the time period for each "count" by about +/-0.5 Seconds. Another jumper sets the timing mode.

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).
