Description
1. Output drive capacity: 250VAC-10A, 125VAC-10A, 30VDC-10A, 28VDC-10A;
2. Easy to use, each group of outputs has a simple 3-wire structure, and 6 output binding posts are reserved;
3. The input is directly connected with the IO port or digital circuit of the single-chip microcomputer, the input high-level relay is engaged, and the input low-level relay is released;
4. The working voltage is 5V, the suction current is about 70mA per channel, and the relay status indicator is provided;
5. Full SMD components, reasonable drive circuit design, 8050 transistor drive relay action;
6. It is equipped with fixing screw holes for easy installation, and the size of the circuit board is 1.8cm*4.0cm*1.9cm, and the weight is 15g;
Simple test instructions: After the input and output of the module are electrically insulated, after the correct voltage is corresponded, only need to connect the high level (such as short circuit with VCC) on the input pin to make the relay engage, and the relay will not operate if it is not connected or connected to the low level (such as short circuit with GND).
