Photo Control Unit

The Photo Control Unit by WEE (Wadia Electronics and Engineering) is an automatic light/darkness-activated switching device designed for industrial and electric applications. It uses a transmitter-receiver system (likely infrared or optical beam-based) to detect objects or light changes and triggers a relay output accordingly.

Control Logic:

  • Type: Transmitter-Receiver System (IR/optical beam break detection)

  • Output: Relay contact (for switching external devices)

  • Indicators:

    • Relay On (shows relay activation)

    • Power On (indicates unit is powered)

How It Works:

  1. Transmitter emits an infrared/optical beam.

  2. Receiver detects the beam.

  3. When the beam is interrupted (object passes) or light conditions change, the relay switches.

  4. The Relay On LED lights up when activated.
