VL-LCR-RL8-A(B) — Automatic Light Control Relay
This automatic light control relay turns electrical equipment on or off based on a set illuminance threshold. It is ideal for corridors, outdoor areas, street lighting, and other applications that require automatic nighttime operation.
The relay supports a wide working voltage range (AC/DC 24–240V) and features an adjustable illuminance threshold for sensitivity control. It comes with a built-in light detection sensor and a compact 18mm width, making it easy to install on standard 35mm DIN rails in control panels and distribution cabinets.
Key Features
- Built-in light sensor turns equipment on/off at a set illuminance threshold
- Type A: instantaneous switching · Type B: 10-second delayed disconnection
- Adjustable sensitivity via rotary control, sensor lead up to 20m
- Reaction time under 1 second
- Mechanical life 1×10⁷ operations
