5V Modbus RTU 4 Channels Relay Module, Input Optocoupler, Isolation RS485 MCU for, Arduino
This board has four 5V relays that can switch high-current devices such as appliances and equipment. You can control it directly with a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic). Each relay needs 50-60mA of driver current. The relays can handle up to AC250V 10A or DC30V 10A of load.
Application:
- Supports all MCU control.
- The industrial field.
- PLC control.
- Smart home control.
Features:
- .Modbus serial communication
- Relay switching output
- Convenient AT command control
