US7-B5-R38 Unitronics Unistream 7" HMI and PLC with 24 digital/2 analog inputs and 12 relay outputs

Why Choose the Unitronics US7-B5-R38 UniStream PLC with Integrated HMI?

The Unitronics US7-B5-R38 is a compact PLC and touchscreen HMI all-in-one controller from the UniStream Built-in series. It combines a programmable logic controller, operator interface and built-in I/O within a single device, reducing control panel wiring and simplifying automation system architecture.

The controller features a 7 inch colour touchscreen display with a resolution of 800 — 480 pixels, providing clear visualisation of machine status, alarms and process data. UniStream controllers are programmed using the UniLogic development environment, enabling engineers to configure PLC logic, HMI screens and communications within one integrated software platform.

The US7-B5-R38 includes built-in I/O comprising 24 digital inputs, 2 analogue inputs and 12 relay outputs. Several of the digital inputs support high-speed counter functionality, making the controller suitable for motion-related tasks such as encoder feedback and positioning applications.
