A ready-built timer module principally designed for use with an alarm bell or siren, but suitable for use in many other applications.The unit features both a 10 minute delay and 20 minute cut-off timer, with the option to disable one or the other, ie. instant activation, then 20 minute relay timer operation, or 10 minute delay, then permanent relay operation.
The unit requires a 12V DC supply and the trigger input can be either +ve or -ve.
An on-board relay provides Common, NC and NO contacts for external siren control.
A test link is also provided, which simulates the normal operation of the timer, but with a 6 second delay and a 12 second activation period.
All connections to the board are via screw terminal connectors.
Power Supply: 12V DC
Dims: 64 x 55mm
Note: An electronic module is a pre-assembled kit. It consists of an instruction pamphlet and a completely assembled circuit board. The instruction pamphlet contains information for using the module. The aim with the modules is to save the end user’s time since all the electronic components are already soldered onto the PCB. It supports the concept of modular electronic system design.
