PRODUCT DESCRIPTION
This module is an 8-channel relay, operating at 12V and using the Modbus RTU protocol via RS485 communication. It incorporates input optocoupler isolation to protect the microcontroller against high voltage spikes. Designed for controlling high-current devices and equipment, it can switch them on or off. The module is versatile and compatible with a range of microcontrollers, including Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, and TTL logic, all of which can directly control its operation. Each relay channel needs a driver current of 50-60mA and can handle loads of up to AC250V 10A or DC30V 10A.
