1 Channel Relay Module with light coupling 5V

A relay is an electrically operated device. It has a control system and (also called input circuit or input contactor). It is frequently used in automatic control circuit. To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal. This 1 Road/Channel Relay Module (with light coupling) 5V module meet the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module. The triggering of 1 Road/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 the relay circuit. Features : Equipped with high-current relay 10A@250VAC / 10A@30VDC. It can control both AC and DC appliances such as
