6
second to 20 minute 12Vdc delay timer board with a relay output (C, NO,
NC).
The countdown starts when power is applied to the board (there is also
a small onboard ON/OFF switch) and will stop after the preset delay time
is reached or the power supply removed.
The relay can be set to either switch from 'On-to-Off' or 'Off-to-On' using an onboard jumper.
The delay time is set using a series of onboard 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).
