8 channel 12V relay module with light coupling

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 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; One often opened a normally closed contact; Blue KF301 terminal line 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 the safe use. Widely used for all MCU control, industrial sector, PLC control, smart home control.
