This 2 Road/Channel Relay Module (with light coupling) 12V module meets the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module. RoboticsBD
The triggering of the 2 Road/Channel Relay Module is reliable, more stable. The double FR – 4 circuit board design, high-end SMT process. It has power and relay operation instructions. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy.
The inputs of the 2 Channel 12V Relay Module are isolated to protect any delicate control circuitry. RoboticsBD
A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.
The use of such high-voltage relay eliminates the risk of heating up of the relay as electromechanical relay limit the current consumption in accordance with a voltage rating. RoboticsBD
The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative
