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.
Specification:
1. VCC: Power interface ,5V
2. GND: Ground
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. Weight: approx. 12g

Note:

1. High level flip-flops shows that there are trigger mode 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 shows that there are 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.
3. Please allow 1-3mm differs due to manual measurement.
4. Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding.
