Features:
1. With isolation groove in control area and load area.
2. With power and relay action indication, bright when connect and go off when disconnects.
3. When there is a signal in signal input, public side and common side will breakover.
4. It can be not only used as a microcontroller development board module, but also as a home appliance control.
5. It can not only control the DC or AC signal, but the 220V AC load.
6. With a permanent open and close vents contact.
7. It is convenient to connect with blue KF301 terminal access control cable.
8.The red light is the power LED indicator light, and the green light is the relay LED indicator light.
9.Low-level triggering refers to a triggering method in which the voltage between the signal input terminal and the ground is OV. It can be understood as a triggering method in which the signal input terminal is short-circuited to the GND negative pole.
