This 12V 8 Channel Relay board meets safety standards as control areas and load areas have isolation grooves. It features an optical coupling isolation module for reliable and stable triggering. The double FR4 circuit board design with high-end SMT process ensures durability and performance.
It has power and relay operation indicators. Relays terminals (C, NC, NO) are accessible through screw terminals, making wiring straightforward. The inputs are optically isolated to protect delicate control circuitry. A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and more can control it.
The use of high-voltage relays reduces the risk of heating since electromechanical relays limit current consumption according to voltage ratings.
