1. The power supply: 5V 2. Module size: 52.8mm x 32mm x 18mm 3. According to the board of the key, or an external button to make the relay module to attract or disconnect, click on the pull, and then press the button to disconnect, low level trigger. Power on again when the relay is in off state. 4.The secondary output end of the relay to withstand the maximum current is 10A, that is the maximum working current cannot be accused of a circuit or device is greater than 10A, according to their own needs to be connected to the normally open or normally closed terminal. 5. Reserved external pull lights welding position, and the board has good welding the attraction indication lamp.
Compatible with arduino etc, 12V relay contact capacity 10A 250V, with optocoupler protection. Onboard power supply module does not need an external power supply. I / O port driver is active low.
Used as a microcontroller development board module can be used as appliance control, can be used as PLC extended output
Apply photosensitive resistance to induct the intensity of the light, can directly control the load with attached relay module
With a potentiometer to adjust the sensitivity, set the start relay thresholds
Output type: Directly connect AC 220V 10A or DC30V 10A
With 4pcs fixed screw holes, convenient to install
PCB size: 5*2.6cm (L*W)
Using wide voltage LM393 comparator
