This 8-Road/Channel Relay Module (with light coupling) 5VDC module meets the safety standard as control areas and load areas have an isolation groove. Optical coupling isolation module.

The triggering of the 8-Road/Channel Relay Module is reliable and more stable. The double FR-4 circuit board design uses a 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 inputs of the 8-channel 5VDC relay module are isolated to protect any delicate control circuitry.

A wide range of microcontrollers, such as Arduino, 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.

Features :

• Equipped with high-current relay (10A at 250 VAC or 10A at 30 VDC)
• It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc
• High-quality screw terminals (Terminal Block) provided (C, NC, and NO) for quick and easy connection
• 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 is common and often starts conduction.
• The relay can directly control all kinds of equipment and loads.
• One often opens a normally closed contact;
• The blue KF301 terminal line is more convenient.
• It is also able to control various appliances and other types of equipment with a large current.
• Red working status indicator lights are conducive to safe use. Widely used for all MCU control, industrial sector control, PLC control, and smart home control.
