230Vac powered 1 to 180 second delay timer module with mains rated relay output. When activated the relay turns on for the user-set time period.
Timer is activated using the Start input (with for example a push button or relay contact closure).
This a non-retriggerable timer - once a countdown has started it will always time-out after the delay time set. Any other activity on the Start input is ignored. The timer resets on timeout and is ready for a new Start input.
An optional INSTANT-ON mode disables the trigger input. In this mode, the the relay turns on and the delay countdown commences immediately power is applied to the board. The relay turns off when the user-set time delay time has elapsed. Power must be removed and reapplied for a fresh countdown to commence. Instant-On mode is set using a header jumper not included (Order Code JUMPER-RED).
The delay time period is adjustable from 1 to 180 seconds using the onboard potentiometers (header pins allow the use of user-supplied external potentiometers if required).
An LED indicates that the timer is in operation.
A TRIAC output version of this board is available (Order Code CI018)
