This is an 8-Channel 5V 10A Relay Module with optocoupler. It can be directly controlled by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It can control various appliances and other types of equipment with large current. Output rating for each relay is 250V/10A AC or 5V/10A DC.

 Triode drive | Increasing relay coil | Strong driving ability | Fixed bolt hole | Easy installation | Diode effusion protection | Short response time | Board mode selection | Real-time working status indicator | Pull-down circuit for avoidance of malfunction | High impedance controller pin

 Relay module:140×58 mm
