PRODUCT DESCRIPTION
This board features four 12V relays designed to switch high-current devices. It is directly controllable through microcontrollers like Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, or TTL logic. Each relay necessitates a driving current of 50-60mA and is capable of handling up to 10A at AC250V or DC30V. Features include:
- .Modbus serial communication
- Relay switching output
- Convenient AT command control
Application:
- Supports all MCU control.
- The industrial field.
- PLC control.
- Smart home control.
