The 12V 4Channel Relay Module double FR4 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 12V 4Channel Relay Module are isolated to protect any delicate control circuitry.
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.
Package includes :
1 x 12V 4Channel Relay Module
