ATC Diversified Tuc-120-Aka-030 replacement part, on-delay time delay relay 110/120v ac/dc, ATC time delay relay industrial control

ATC Diversified Time Delay Relay (TDR) for industrial control applications. Introduces a precise, adjustable time delay between an input signal and an output relay action used to sequence equipment starts, suppress nuisance trips, add hold-on times, and control process timing.

🔍 Application & Benefits

✖ Problems It Solves

  • ✖ Equipment starting simultaneously causing power inrush problems
  • ✖ Nuisance trips from brief signal interruptions requiring time filtering
  • ✖ Process requiring a defined delay between a trigger and an action
  • ✖ Motor needing hold-on time after stop command for controlled coast-down

✓ Key Benefits

  • ✓ Adjustable time delay from milliseconds to hours depending on model
  • ✓ Plug-in socket or DIN rail mounting for control panel flexibility
  • ✓ Multiple timing modes available: on-delay, off-delay, interval, and single-shot
  • ✓ LED status indication shows power-on and output-energized states
  • ✓ Wide input voltage range on universal models

🔧 Installation Overview

  1. Select correct TDR model for the required timing mode (on-delay, off-delay, etc.)
  2. Install in compatible plug-in socket or mount directly per model instructions
  3. Connect supply voltage to power input terminals
  4. Wire trigger/start input to control signal source
  5. Wire output relay contacts to the controlled load or next control element
  6. Set time range and adjust setpoint using front panel controls
  7. Apply power and verify timing function measure delay with stopwatch

❓ Common Questions

Q: What is the difference between on-delay and off-delay?

A: An on-delay (also called delay-on-energize) starts timing when the input is energized and closes the output relay after the set delay. An off-delay (delay-on-release) energizes the output immediately when the input closes, then holds the output on for the set delay period after the input opens. On-delay is used for sequenced starts; off-delay is used for hold-on or run-on applications.

Q: What is an interval timer?

A: An interval timer (also called a one-shot timer) energizes the output relay for a fixed time period when triggered by an input signal, then de-energizes regardless of whether the input is still present. The output on-time is determined only by the set interval, not the input duration.
