About UEB 12V One 1 Channel Relay Module Optocouple Board

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, 12V 2. GND: Ground 3. IN: Control interface .Drive Current at least 4mA 4. COM: Control circuit ground ,Connect to GND 5. Single Size: approx. 44 x 16 x 16mm/ 1.73 x 0.62 x 0.62'' 6. Single Weight: approx. 11g 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. 1 x One Channel 12V Relay Module Shield
