Product Description
| Product Specifications Product Name: Photosensitive Relay Module Product Model: XH-M131 Input Voltage: DC 12V Output Type: Output Switch Control Capacity: Maximum 10A Detection Frequency: 1MHz Dimensions: 53*31*19mm |
| Board Parameters 1. The module uses a 12V power supply and has reverse polarity protection, ensuring reverse power will not damage the module. 2. Normally open port load capacity: AC 0V--125V/20A, DC 0V--14V/20A. The module's output terminal has three ports: common (COM), normally open (CK), and normally closed (CB). These three ports act like a two-way switch. When the relay coil is energized, the common terminal connects to the normally open terminal; when de-energized, the common terminal connects to the normally closed terminal. The COM terminal is typically connected to the negative terminal of the power supply through the load, and the normally open terminal to the positive terminal. |
| The module can be used for light detection and brightness detection. It has a power indicator light (red) and a relay pull-in indicator light (red). It also has four M3 screw mounting holes, which greatly facilitates installation. The board can adjust the photosensitivity through a potentiometer. It has its own relay and can be used for various brightness detection control switches. It can be used in, for example, street lights, which automatically turn on at night and turn off during the day, as well as other equipment that requires automation. |
