Easy to use, each output group has a simple 3-wire structure, and 6 output terminals are reserved.
The input is directly connected to the MCU IO port or digital circuit, and the input high-level relay The device is closed, and the input low level relay is released.
Working voltage 5V, pull-in current about 70mA per circuit, with relay status indication light.
Full chip components. Reasonable drive circuit design, using 8050 transistor to drive the relay Electrical action.
There are fixed screw holes for easy installation,
module size: 25.8*33.4*16.7mm. Test Instruction The input and output of the module are electrically insulated.
After the correct voltage is supplied, you only need to Connecting a high level (such as a short circuit with VCC) to the input pin can make the relay pull in,If not connected or connected to low level (such as short-circuit with GND), the relay will not operate.
