KY-019 5V Single Channel Relay Module Shield Compatible With PIC AVR DSP ARM And Arduino Controllers
The relay coil drive voltage is 5V, and the input control level can also be within 5V
Module description:
1. Output drive capacity: 250V AC-10A, 125V AC-10A, 30V DC-10A, 28V DC-10A;
2. Easy to use, each output group has a simple 3-wire structure, and 6 output terminals are reserved;
3. The input is directly connected to the I0 port of the single-chip microcomputer or digital circuit, and the input high-level relay is pulled in and the input low-level relay is released;
4. The working voltage is 5V, the pull-in current is about 70mA per channel, with relay status indicator;
5. Full chip components, the most reasonable drive circuit design, using 8050 transistor to drive the relay action;
6. There are fixed screw holes for easy installation, and the size of the circuit board is 1.8cm*4.0cm*1.9cm.
Simple test description: The input and output of the module are electrically insulated. After the correct voltage is supplied, you only need to connect a high level (such as a short circuit with VCC) to the input header. The relay can be closed, not connected or connected to a low voltage Level (such as short circuit with GND) relay does not operate.
