Description

RS485 8 Input Modbus Module

The RS485 Converter for TTL Digital Pins, CMOS, IO Modbus RTU is an electronic device widely used for communication between machines and sensors, acting in order to send the data received by the digital sensors to a computer or other equipment with RS485 communication.

For power supply, it is necessary to use direct voltages between 6 and 24VDC (12V is recommended) via screw terminals, identified on the board as “GND” and “VIN”, since the RS485 communication (compatible with Modbus RTU) is carried out by the same type of terminals, but identified as “B-” and “A+”.

It is important to remember that for communication with the computer you will need to use a CH340 USB to RS485 Converter (not included), and you can also opt for a RS485 to Ethernet TCP/IP Converter (not included) and thus have the data on the Internet.
