2 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 5V Dual Channel Relay Module (with Light Coupling) meets the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module.
The triggering of the 2 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.
Features :
- Equipped with high-current relay 10A@250VAC / 10A@30VDC.
- It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc.
- High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection.
- A freewheeling diode to protect your microcontroller.
- Input Signal Pin connected to Burg stick for easy accessibility.
- LED status indicators to indicate the relay ON/OFF status.
- Mounting holes provided.
- Signal input with a high-level signal, the common and often start conduction.
- The relay can directly control all kinds of equipment and load.
- Blue KF301 terminal line more convenient.
