Modbus RTU (RS-485)

Modbus RS-485 input and output modules

In this part of our store you will find industrial I/O modules with Modbus communication protocol and RS-485 interface, used to extend existing systems with additional resources of digital or analog inputs / outputs. Extension modules are most often used in control systems in which the central units are PLC or industrial computers, therefore the RS485 interface and the Modbus RTU protocol are used for communication.

Learn more about Modbus RS-485 I/O modules

Our I/O modules are devices that communicate with the most popular PLC devices and devices that support the MODBUS MASTER protocol. In addition, they have (depending on the model) digital or analog inputs and convenient wire connectors.

For your convenience, we have divided the input and output modules into three basic categories depending on the type of inputs and outputs they support and having a temperature input. Thanks to this division, your purchases will be easier and you will find faster the Modbus RS-485 module that interests you.
