8 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 8 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 8 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.
