This product is a 1-channel relay module board, which is 5V active low. The Relay Module receives the infrared remote control signal of two keys, and output thought the 1 channel 5V Relay after decoded by the MCU. And the load of the Relay are 250VAC-10A.125VAC-10A.30VDC-10A.28VDC-10A, which can drive the most of household appliances or other devices to achieve the ability of control these devices.

Working voltage: 5V Control distance: 8m The Relay Board has the 3mm screw holes for easy installation. Relay Module interfaces: VIN + Positive pole 5V, GND Negative electrode; the middle port of the three ports is Community port, the other two ports are normally open port and normal close port (the front end circuit of the relay output and input is insulative).
