1 Channel 5V Relay Module 1-Channel realy KY-019
1. Output drive capability: 250VAC-10A, 125VAC-10A, 30VDC-10A, 28VDC-10A;
2, easy to use, each group outputs a simple 3-wire structure, reserved 6 output terminals;
3. The input is directly connected with the IO port or digital circuit of the single chip microcomputer. The input high level relay is connected, and the input low level relay is released.
4, working voltage 5V, pull-in current about 70mA each way, with relay status indicator;
5, full patch components, the most reasonable drive circuit design, using 8050 triode to drive relay action;
6, with a fixed screw hole for easy installation, circuit board size 1.8cm * 4.0cm * 1.9cm, weight 15g;
Simple test description: The module input and output are electrically insulated. After the correct voltage is applied, it is only necessary to connect the input pin to a high level (such as short circuit with VCC) to make the relay pull in, not connected or connected to low level. (If shorted to GND) The relay does not operate.
