Multi-Mode Delay Timer, 13A Relay, Isolated Input

Product Formats Available: Pre-Assembled Module (AS) or
Self-Assembly Electronic Kit ( Soldering Required)

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
• Please see User Manual for full explanation of the Timing Modes

• Four time bases
  • 1 - 255 Seconds
  • 10 - 2550 Seconds
  • 1 - 255 Minutes
  • 10 - 2550 Minutes
• On-board DIP switches for all settings (Timing Mode and Delay Time)
• Opto-isolated Trigger Input
  • Make contact
  • Open collector
  • External voltage (6-81V)
• Auto-start on power-up if trigger signal present (all modes)
• Reset Input
• 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.

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.
