1 Channel Relay Module Board Shield 5V/12V
1. This module complies with international safety standards, and the control area and the load area have isolation slots;
2. using genuine relays;
3. with power and relay action instructions, the light is closed, the light is off;
4. When there is a signal at the signal input end, the common end and the normally open end will be turned on;
5. can be used as a microcontroller development board module, can be used as home appliance control;
6, control DC or AC signal, you can control 220V AC load;
7. There is a normally open and a normally closed contact;
8. The blue KF301 terminal is more convenient to connect to the control line.
The high level trigger refers to the trigger mode of the voltage between the signal input terminal and the ground, which can be understood as a way to trigger the short circuit of the signal input terminal and the VCC positive terminal;
Low-level triggering refers to the triggering mode of the voltage between the signal input terminal and ground is OV, which can be understood as a way to trigger the short circuit of the signal input terminal and the GND negative terminal.
