Description
1 Channel 24V Relay Module
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 1 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 relay is safely driven by transistor BC547 hence your input device, such as Arduino, is protected from relay circuit.
