Arduino 4 Channel Low Level Relay Module with light coupling 5V meets the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module. The triggering of 4 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 4 Channel 5V Relay Module are isolated to protect any delicate control circuitry.
