New improved performance

Highly versatile microcontroller based Multi-Mode Timer featuring seven different timing modes that cater for a good variety of applications. Crystal controlled circuit for accuracy. Opto-isolated Trigger input. 13 Amp high current mains rated relay output.
Timing Modes - Mode 1: Instant On, Delayed Off, Level Triggered
Relay activates on trigger. Loss of trigger deactivates relay and resets timer ready for next trigger signal - Mode 2: Instant On, Delayed Off, Edge Triggered, Re-triggerable
Relay activates on trigger. Loss of trigger does not affect timing cycle. A new trigger signal during timing cycle restores full delay time. Relay releases on timeout and timer resets - Mode 3: Delayed On and Hold, Level Triggered
Relay actives at end of delay time. Loss of trigger signal at any point of the timing cycle resets timer - Mode 4: Instant On and Hold, Delayed Off (Retriggerable)
Relay activates on trigger. Timing cycle starts on loss of trigger signal. Full delay time is restored each time a new trigger input is received during countdown. Countdown starts again on loss of trigger signal. Relay releases on timeout and timer resets if no new trigger input is received during countdown - Mode 5: Toggling - Pulse/Pause
While trigger signal is present relay repeatedly cycles On then Off with same time period for pulse and pause phases. Loss of trigger immediately deactivates relay and resets timer - Mode 6: Instant On, Delayed Off with Pause
Similar to Mode 1 except loss of trigger signal pauses the delay countdown and relay remains on. Countdown resumes from where it was paused when trigger is reapplied. Relay deactivates on timeout and timer resets - Mode 7: Delayed ON with Pause, 2 Second Pulse, Level Triggered
Trigger starts delay countdown but relay remains off. At end of delay time relay pulses on for 2 seconds. This cycle repeats endlessly. Loss of trigger signal pauses delay countdown. Hardware reset required to exit timing cycle - Please see User Manual for full explanation of the Timing Modes
