V350-J-TR20 Unitronics Vision 3.5" graphic display and keypad HMI and PLC onboard I/Os accepts I/O expansions up to 512 I/Os

Why Choose the Unitronics V350-J-TR20 Vision PLC + HMI?

The Unitronics V350-J-TR20 is a powerful all-in-one PLC with integrated touchscreen HMI from the Vision350 series, designed to simplify industrial machine control. By combining logic processing, operator interface and onboard I/O in a single compact device, it reduces wiring complexity, panel space requirements and engineering costs in automation systems.

The controller features a 3.5 inch colour touchscreen display that allows operators to monitor system status, view alarms and interact directly with machine processes. Built-in I/O provides immediate connectivity to sensors, actuators and field devices, while expansion modules allow the system to grow to larger automation architectures when required.

Unitronics Vision PLCs are widely used by machine builders because they combine PLC programming, HMI design and communications within a single development environment. This reduces integration effort while enabling advanced features such as data logging, remote monitoring and industrial network communication.
