May not be exact product—for reference only.
- Family: TIME DELAY RELAY
- Function: TRIGGERED ON DELAY
- Timing Range: 1.2 - 120 min
- Control Voltage: 240V AC
- Output: 10A DPDT
Description Of Function
Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the time delay (t) begins. At the end of the time delay (t), the output is energized and remains in that condition as long as either the trigger is applied or the input voltage remains. If the trigger is removed during the time delay (t), the output remains de-energized & the time delay (t) is reset.
