Why Choose the Unitronics UAC-CX-01RS4 RS485 Communication Module?
The Unitronics UAC-CX-01RS4 is a compact RS485 communication expansion module designed for the Unitronics UniStream PLC platform. It enables UniStream built-in controllers to communicate with industrial devices and field networks using the widely adopted RS485 serial communication standard.
This Uni-COM CX module snaps directly onto compatible UniStream controllers, including the US5, US7 and US10 series. Once installed, it provides a galvanically isolated RS485 interface that supports multi-drop communication networks commonly used in industrial automation systems.
The module is frequently used to connect PLCs with drives, remote I/O modules, sensors and other automation equipment using protocols such as Modbus RTU. It also supports long communication distances and multi-node networks, making it suitable for distributed control systems across factories and production lines.
