   Description
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: Ground3. IN: Control interface .Drive Current at least 4mA4. COM: Control circuit ground ,Connect to GND5. Single Size: approx. 44 x 16 x 16mm/ 1.73 x 0.62 x 0.62''6. Single Weight: approx. 11gNote: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.5 x One Channel 12V Relay Module Shield
