Time Delay Relays Component Intelligence

Precision timing modules for industrial sequencing and control loops.

What are Time Delay Relays components?

Time delay relays combine a relay with a timing circuit to control industrial processes. Select based on timing function (e.g., delay-on-make), input voltage, contact configuration, and time range. Ensure the relay's switching capacity matches your load requirements.

How to Choose Time Delay Relays Components

Selecting the right relay requires matching the timing logic to your control sequence and ensuring the output handles your load.

  1. Timing Function

    Define the logic: Delay-on-make, delay-on-break, single-shot, or interval. Mismatching the function is the most common design error.

  2. Input Voltage

    Verify the control voltage (AC/DC) and tolerance. Industrial environments often require wide-range inputs to handle supply fluctuations.

  3. Contact Configuration

    Select SPDT or DPDT based on the number of circuits to be switched and the required isolation.

  4. Time Range

    Ensure the adjustable range covers your required delay. Fixed-time relays offer higher reliability, while adjustable ones offer flexibility.

  5. Load Switching

    Check the current and voltage ratings of the output contacts against your inductive or resistive load.

Frequently Asked Questions

Delay-on-make starts the timer when the input is energized, closing the contacts after the delay. Delay-on-break requires a trigger signal to open the contacts after a set time once the input is removed.
