US7-C5-RA28 Unitronics Unistream 7" HMI and PLC with 14 digital/2 analog inputs, 8 relay and 2 analog outputs

Why Choose the Unitronics US7-C5-RA28 UniStream PLC + HMI?

The Unitronics US7-C5-RA28 is a versatile all-in-one PLC and touchscreen HMI controller from the UniStream Built-in series. It combines a high-performance programmable logic controller with a 7-inch colour touchscreen HMI, providing an efficient solution for machine automation, monitoring and operator control in industrial environments.

This model includes a comprehensive built-in I/O configuration with 14 digital inputs, 2 analogue inputs, 2 temperature inputs, 8 relay outputs and 2 analogue outputs. The digital inputs support high-speed counters for pulse signals, while relay outputs allow switching of industrial loads such as contactors and solenoid valves. Temperature inputs enable direct connection of RTD or thermocouple sensors for process monitoring and control.

As part of the UniStream platform, the controller supports advanced automation functions including PID control, alarms, data logging, trends and recipe management. Built-in UniCloud connectivity enables secure remote monitoring and data collection, helping engineers integrate machines into modern IIoT and Industry 4.0 environments.
