Item # 021-120-0010, 1 to 10 Second Delay Range Timer
List Price $129.45

Time Delay Relay
The 021 Timer offers a delay on operate function. The timing range of the Adjustable Delay Timer is user specified up to one hour. The Delay on Operation can be manually set to any time within the selected range. Timing is initiated by application of power to the Time Delay. Upon completion of the timing cycle, the output relay will energize.

Installation Instruction
  1. Connect pins 2 and 7 of the timer to a single phase AC supply as shown in the installation diagram at left.
  2. The “HOT” side of the AC voltage is connected to pins 1 and 2. One side of the contactor is connected to pin 3 and its opposite side is connected to Neutral at pin 7.
  3. The second set of contacts in the timer - pins 5, 6 and 8 are not used in this example.


Test Method

A single phase AC line and properly rated light bulbs are needed to test the delay on operate timer.

  1. The AC line and light bulbs must be connected to the timer as shown in the test method diagram at the bottom left.
  2. When the power switch is turned on, AC power is applied to the timer and the timing cycle begins. The light bulbs will illuminate when the timing cycle is complete. A stopwatch can be used to verify the timing accuracy.
