Here is a board that, when triggered, will activate a relay for a specified period of time.  This time is controlled by a “timing resistor” which is easily replaceable by the user.  The trigger can be a switch closure (supplied by User) or if you remove the “pullup resistor” (see diagram on Info Sheet), the board can be triggered by touching your finger to wires coming from the trigger terminals.

Here is a board that, when power is applied, will cycle on and off a relay.  The relay on time and off time can be independently controlled.  The relay will continue cycling on and off until the power to the board is turned off.

Cascading Timer Relay Board: $20.75

Here is a board with two 10A relays that, when triggered, will activate one relay for a specified time and then activate another relay for a specified time.  Each relay’s ON time can be independently controlled.  Once the second relay’s time has expired both relays will remain off until the board is triggered again.

Multi-Event Timer Relay Board: $39.00

Here is a board that I developed for someone who set up haunted houses.  This person wanted a board that would control 3 separate events – a “Bang Event” that happened as soon as someone triggered the board, a “Show #1” that occurred for a specified period of time and a “Show #2” that occurred for a specified period of time that started after Show #1 finished.  He also wanted the board to isolate itself from the triggering event so that it could not be re-triggered until after the last event had completed.
