The precision 1-channel photo-relay module adopts genuine high-quality industrial-grade components, military-grade double-sided PCB board, and has two-color LED signal indicator; the layout is comprehensive, the module performance is stable, and it can be widely used in various brightness measurement and control occasions.
1>.The brightness threshold is adjustable (the sensitivity is adjustable), and the on-board brightness threshold potentiometer can be adjusted according to different needs.
2>.Waterproof light sensor head, can be used outdoors, effectively prevent outdoor weathering and weathering invading the sensor head, greatly increasing the service life.
3>.With normally closed normally open terminals, can use different terminals according to different needs.
4>.With reverse connection protection (to prevent reverse firing chips), to prevent accidental reversal, burning circuit.
5>.Intelligent adjustment design, when the relay is activated, automatically fine-tune the action threshold, solve the problem of repeated action of the critical value, and prevent the critical point from repeatedly switching.
1>.Input Voltage: DC 12V
6>.Over Current Protection:Yes
7>.Short Circuit Protection:Yes
1pcs DC 12V Photosensitive Sensor Controller Relay Driver
