US5-C5-R38 Unitronics Unistream 5" HMI and PLC with 24 digital/2 analog inputs and 12 relay outputs with Unicloud included

Why Choose the Unitronics US5-C5-R38 UniStream 5" PLC + HMI?

The Unitronics US5-C5-R38 is a powerful UniStream built-in PLC with integrated 5-inch touchscreen HMI and onboard I/O, designed for advanced machine control and industrial automation systems. By combining PLC logic, visualisation and flexible I/O in a single compact unit, it simplifies control panel architecture while reducing wiring, hardware costs and installation time.

Part of the UniStream Built-in series, the controller integrates a high-resolution colour touchscreen with a powerful PLC engine and extensive communication capabilities. It supports industrial networking protocols and cloud connectivity through the Unitronics UniCloud IIoT platform, enabling remote monitoring, diagnostics and data collection for modern smart-factory applications.

The US5-C5-R38 includes 24 digital inputs, 2 analogue inputs and 12 relay outputs, allowing direct connection to sensors, actuators and control circuits. Its scalable architecture allows expansion up to thousands of I/O points using UniStream expansion modules for larger automation systems.
