Features:
1. This module complies with international safety standards, and there are isolation slots between the control area and the load area;
3. With power supply and relay action indication, it is bright when it is pulled in, and it is not bright when it is disconnected;
4. When there is a signal at the signal input terminal, the common terminal and the normally open terminal will be connected;
5. It can be used as a microcontroller development board module, and can be used as home appliance control;
6. Control DC or AC signal, can control 220V AC load;
7. There is a normally open and a normally closed contact;
8. It is more convenient to connect the blue KF301 terminal to the control line.

Specifications:
1. Power supply to meet the scope , DC 5V-12V
2. The power required by the by -line diagram , is not reversed , although the protection circuit , but not for a long time reversed ;
3. Product regulator slight fever is a normal phenomenon , long working hours have a normal relay heat phenomena are normal ;
4. Relay load power to give leave some margin should avoid high-power ( about 2000W) and long working environment , there will be some impact on the life of the product

Usage:
Press the trigger button , the relay is locked , press again , the relay off , you can also add the trigger switch , and the use of low-level trigger.
Control appliances, home of various lighting control, factory equipment control , current control for a variety of small high-voltage power control products.
