We have our own factory,If you have the industrial products you want, you can find us, and we will try our best to help you find the products you want. We can help you produce the products you want. We also have a complete product supply system. For any product you want, please contact customer service. The customer service time is from 9 am to 8 pm. Welcome to consult. 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 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. Package: 1 x 1 Channel 5V Relay Module Shield
