US5-B5-R38 Unitronics Unistream 5" HMI and PLC with 24 digital/2 analog inputs and 12 relay outputs

Why Choose the Unitronics US5-B5-R38 UniStream PLC with Integrated HMI?

The Unitronics US5-B5-R38 is a compact PLC and touchscreen HMI all-in-one controller from the UniStream Built-in series. It integrates a programmable logic controller, operator interface and built-in I/O within a single panel-mounted unit, reducing wiring complexity and control cabinet space in industrial automation systems.

The controller features a 5 inch colour resistive touchscreen display with an 800 — 480 WVGA resolution, allowing operators to monitor alarms, process data and machine status through a clear graphical interface. Engineers can configure PLC logic, HMI screens and communications using the UniLogic development environment, enabling complete automation projects to be developed within one integrated software platform.

The US5-B5-R38 includes built-in I/O consisting of 24 digital inputs, 2 analogue inputs and 12 relay outputs. Four of the digital inputs support high-speed counter operation for encoder or pulse measurement tasks, making the controller suitable for demanding industrial automation applications.
