The TIM-01 Universal Timer Module has been designed to provide eight field-programmable functions controlling an SPDT relay from 1 second to 99 days. Powered by 12v DC this unit caters for either positive or negative triggers and incorporates Fail Safe and Fail Secure operation.
Four banks of DIP Switches are provided for programming operation mode.
- One-Shot - Applying trigger activates relay for the selected time. Trigger input must be removed and reapplied to reactivate.
- One-Shot Retriggerable - As for One-Shot except where the input is retriggered the timer starts again.
- Strobe Reset - Requires momentary trigger to be applied, the relay will activate for preprogrammed time.
- Clutch Relay - Applying trigger voltage causes the relay to change state. Remove and reapply trigger forces the relay to change state. No timing function in this mode.
- Programmed Pulse - Applying trigger causes relay to operate for one second at intervals selected on dipswitches. Operation ceases when the trigger is removed.
- Debounce - Applying trigger causes relay to activate for the programmed time. The relay remains activated until timeout, regardless of the trigger is removed. If input remains triggered after a timeout, the relay remains activated until the trigger is removed.
- Stand-Off Timer - Ideal for DOTL alarms. Timing commences when the trigger is applied. If the trigger is removed before time out, the relay will not activate. If trigger remains after time out, the relay will activate.
- Fail Secure - The relay does not change state during a power failure.
- Fail-Safe - The relay is energised when the trigger is not active. The relay will de-energise, releasing power to the door locks during a power failure.
