3. IN: Control interface. Drive Current at least 4mA
4. COM: Control circuit ground, Connect to GND
5. Size: approx. 41 x 16 x 16mm/ 1.61 x 0.62 x 0.62''
6. With isolation groove in the control area and load area.
7. With power and relay action indication, it is bright when connected and goes off when disconnected.
8. When there is a signal in signal input, the public side and common side will break.
9. It can be not only used as a microcontroller development board module but also as a home appliance control.
10. It can not only control the DC or AC signal but also the 220V AC load.
11. With a permanent open and close vents contact.
12. It is convenient to connect with a blue KF301 terminal access control cable.
Note:
1. High-level flip-flops show that there are trigger modes of the voltage between the signal input terminal and the ground; That is to say it is a way of short circuit trigger between signal input and VCC positive pole.
2. Low-level flip-flops show that there is voltage for OV trigger mode between the signal input terminal and the ground. In a word, it is a way of short circuit trigger between signal input and GND negative pole.
