2 Channel 12V Relay Board
This 2 Road/Channel Relay Module (with light coupling) 12V module meets the safety standard as control areas and load areas have the isolation groove. It is important that the microcontroller share ground with the relay board along with other control signals else it will not able to control the relay. Very useful project for applications like Micro Controller based projects, Remote controllers, Lamp on Off, and any circuits which required isolated high current and high voltage switching by applying any TTL or CMOS level voltage.
