Timer Control Unit

WEE Timer Control Unit – 230V, 30s Range (PNP Proximity Sensing)

This Timer Control Unit by WEE (Wadia Electronics & Engineering) is an industrial-grade, time-delay relay module with PNP proximity sensor input and a 30-second adjustable timer. It is designed for automated switching applications in electric industries.

🔹 How It Works

  1. PNP/NPN Proximity Sensor detects an object (metal/non-metal, depending on sensor type).

  2. The timer circuit activates, delaying the relay output for up to 30 seconds.

  3. After the set delay, the relay switches (ON/OFF), controlling connected devices (motors, solenoids, lights).

🔹 Applications

✔ Time-Delay Switching (conveyors, pumps, machinery)
✔ Automated Batch Processing (industrial mixing, filling systems)
✔ Safety Interlocks (delay before machine start/stop)
✔ Motor Control (soft-start, delayed shutdown)
