- Delay on operate
- Timer relay module with 1 changeover, width 23 mm
- Supply: 200V – 420V DC in 2 ranges
- Control LED for energised relay
- ZR4 is a delay on operate timer relay for a wide DC voltage range.
- The time range is 0.1-1.0 seconds.
- The time is set by the front panel potentiometer
NOTES ON CONNECTION
- Supply voltage 1 is connected to terminals A and B.
- Supply voltage 2 is connected to terminals C and B.
- The changeover is located at terminals:
– F common
– E normally open contact and
– G normally closed contact
- Delay on operate: When the set time elapses, the contact closes between F and E after application of the supply voltage.
