This 1 Channel 24V Relay Module with Optocoupler meet the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module. The triggering of the 1 Channel Relay Module is reliable and more stable. The double FR 4 circuit board design, is a high-end SMT process. It has power and relay operation instructions. Relay terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor BC547 hence your input device, such as, is protected from the relay circuit. The inputs of the 1 Channel 24V Relay Module are isolated to protect any delicate control circuitry. A wide range of microcontrollers such as AVR, PIC, ARM and so on can control it. The use of such a high-voltage relay eliminates the risk of heating up the relay as an electromechanical relay limits the current consumption in accordance with a voltage rating.
