PRODUCT DESCRIPTION
This is an 8-channel relay module operating at 12V, utilizing the Modbus RTU protocol over RS485 communication. It features input optocoupler isolation to safeguard the microcontroller from high voltage spikes. This module is designed to control high-current devices and equipment, turning them on or off. It is versatile, compatible with various microcontrollers including Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, and TTL logic, which can directly manage its operation. Each relay channel requires a driver current of 50-60mA and can handle loads up to AC250V 10A or DC30V 10A.
