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.
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 Relay activates on trigger. Timing cycle start on loss of trigger signal. Relay releases on timeout and timer resets
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

Crystal controlled circuit for accuracy
Mains rated relay output with NO, NC, C connections
DC pass-through output (V-Out = V-in i.e. 12Vdc)
LED indicators for Power and Relay
DIN-RAIL compatible PCB footprint
Triggering options include simple push buttons, electrically isolated voltage switching sources or taking the output from our counter and timer kits like 3129 and 3154.
Timing Modes (see User Manual for detailed operational description)
1: Instant On, Delayed Off, Level Triggered 2: Instant On, Delayed Off, Edge Triggered (Re-Triggerable) 3: Delayed On and Hold (loss of trigger signal aborts and resets timer) 4: Instant On and Hold, Delayed Off 5: Toggling (cycling On/Off - same time period) 6: Instant On, Delayed Off, Edge Triggered, with Pause 7: Delayed ON with Pause
NEW 8 Mode version available (see Order Code AS3141-HP-8Mode below): The operation of the extra mode in this version is similar to Mode 3 above but the trigger signal logic is reversed so while trigger signal is present timer is inactive. Loss of the trigger signal starts the countdown delay. Relay turns on at the end of the delay time. Restoration of the trigger signal at any point resets the timer and deactivates relay if active. Useful for a delayed activation output when a control signal drops out e.g. warning buzzer, etc.
