US5-C5-RA28 Unitronics Unistream 5" HMI and PLC with 14 digital/2 analog inputs, 8 relay and 2 analog outputs with Unicloud included

Why Choose the Unitronics US5-C5-RA28 UniStream 5" PLC + HMI?

The Unitronics US5-C5-RA28 is a compact UniStream built-in PLC with integrated 5-inch touchscreen HMI and advanced onboard I/O, designed for sophisticated machine control and industrial automation systems. By combining PLC processing, operator interface and flexible I/O channels in a single device, it simplifies panel architecture while reducing wiring and installation time.

Part of the UniStream Built-in series, this controller offers powerful automation functionality including data logging, PID control, alarms, recipes and remote monitoring. The platform supports industrial communication protocols and remote connectivity through the integrated Unitronics UniCloud IIoT platform, enabling engineers to monitor and manage machines from anywhere.

The US5-C5-RA28 includes an advanced built-in I/O configuration with 14 digital inputs, 2 analogue inputs, 2 temperature inputs, 8 relay outputs and 2 analogue outputs. This flexible architecture allows direct connection to sensors, actuators and process instrumentation while supporting expansion up to thousands of I/O points using UniStream expansion modules.
