8 pin timer relay wiring
Learn the pin configuration and wiring method for an 8‑pin timer relay to control loads with a delay. Includes coil connections, NO/NC contacts, and timing logic.
Wiring Formula Summary:
Relay Coil Voltage: V = IR
(Use Ohm’s Law to check relay current requirement)
Delay Function: Depends on timer module — ON Delay or OFF Delay logic.
- Pin 2 & 7: Coil connections
- Pin 1: COM 1 → Pin 3 NO, Pin 4 NC
- Pin 8: COM 2 → Pin 6 NO, Pin 5 NC
timer relay wiring diagram
An 8‑pin timer relay is used to control electrical loads with a preset delay using a DPDT contact arrangement. It provides both normally open and normally closed outputs across two separate channels. Understanding its pin configuration helps ensure safe and efficient circuit wiring for motors, lamps, and automation systems.
