12V Photoelectric Resistor Relay Module

Automated Light-Controlled 12V Relay Switching: Uses an onboard light-dependent photoresistor (LDR) to automatically switch connected high-power loads on or off based on ambient light levels.

Onboard Sensitivity Potentiometer: Equipped with a precision multi-turn trimmer to easily set the exact light activation threshold for custom dark or light triggering.

High-Power Load Switching Capacity: Outfitted with heavy-duty relay contacts capable of switching up to 250V / 10A AC or 30V / 10A DC electrical circuits.

Integrated Circuit Isolation Protection: Built-in optocoupler and diode isolation protect upstream control systems and power rails from inductive switching spikes.

Dual Status LED Telemetry: Features onboard LEDs for immediate visual confirmation of 12V power input and active relay coil actuation.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with heavy-duty blue screw terminal blocks and a sealed 12V relay enclosure.

Technical Specifications:

Operating Voltage: 12.0V DC.

Relay Output Capacitance: AC 250V / 10A, DC 30V/10A.

Color: Blue PCB with Blue Relay Enclosure and Screw Terminals.

Usage Advice: Connect a 12V DC power source to VCC and GND terminals; wire your high-power load through Normally Open (NO) or Normally Closed (NC) screw terminals, then calibrate the sensitivity potentiometer.

Maintenance: Ensure terminal screws remain tightly fastened; keep circuit components dry and clear of dust or metallic fragments.

Essential Automotive & Solar Light Switch: Position as a plug-and-play, standalone light switch module requiring no MCU programming—ideal for 12V automotive lighting, solar battery systems, and outdoor nightlamps.

Highlight Direct 12V Power Compatibility: Emphasize how direct 12V operation makes it ideal for off-grid power setups, RVs, marine applications, and outdoor solar lighting arrays without voltage step-down converters.

Recommended Cross-Sell Add-ons: Pair with 5V Photoelectric Resistor Relay Module, XH-M131 5V Photo-resistor Relay Module, 4Pin Photoresistor Light Detection Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
