1. New 5V relay module
2. Can be used as a microcontroller development board module, can be used for home appliances control
3.5V-12V to TTL control signal
4. Can control signal DC or AC, 220V AC load.
5. One normally open contact and one normally closed contact
.6. One power indicator
7. A control indicator, unplugged, disconnected not lit
8. Transistor driven, increasing the high impedance of the control pin of the relay coil.
9. The control pin has a pull-down circuit to prevent the relay from becoming vacant if it fails.
10.SKU:1PCS/5PCS+3pcs 10CM Dupont Line
. Relay coil drive voltage is 5V, input control level can also be within 5V. Module description.
Pin definition
1. Output drive capability: 250VAC-10A, 125VAC-10A, 30VDC-10A, 28VDC-10A.
2. Easy to use, each output group has a simple 3-wire structure, and retains 6 output terminals.
3. Inputs are directly connected to the IO port of the microcontroller or digital circuit, input high level relays are closed, low level relays are released.
4. The operating voltage is 5V, the current of each circuit is about 70mA, and there is a relay status indicator.
5. Full chip assembly, the most reasonable drive circuit design, using 8050 transistors to drive the relay action.
6, with fixing screw holes, easy to install, the board size is 1.8cm * 4.0cm * 1.9cm, weight is 15g.
A simple test note: the module is electrically insulated between input and output. Once the correct voltage has been supplied, simply connecting a high level (e.g. shorted to VCC) to the input pin will cause the relay to engage, rather than connecting or connecting a low level (if shorted) using GND) the relay will not operate.
Input section.
VCC: connects to the 5V positive supply
GND: connects to 5V negative supply
Package includes.

The contact gets stuck when switching to 220V, and it would be understandable if the load was high, but no, it's just a regular 10-watt diode bulb. Extremely dissatisfied with these relays.
