PRODUCT DESCRIPTION
This product is a relay module with 8 channels that operates on 12V and uses Modbus RTU protocol with RS485 communication. It has input optocoupler isolation to protect the micro-controller from high voltage. It can be used to switch on or off various devices and equipment that require high current. It is compatible with different types of micro-controllers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic) that can control it directly. Each relay channel needs 50-60mA of driver current and can handle up to AC250V 10A or DC30V 10A of load.
