V350-J-TR34 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-TR34 Vision PLC + HMI?

The Unitronics V350-J-TR34 is a compact PLC with integrated touchscreen HMI from the Vision350 series, designed for industrial machine control and OEM automation systems. By combining the controller, operator interface and I/O into a single unit, the device simplifies control panel design while reducing wiring, hardware costs and engineering time.

The controller features a 3.5 inch colour TFT touchscreen that allows operators to monitor system performance, view alarms and interact with machine processes directly. The integrated I/O enables direct connection to sensors, switches, actuators and other field devices, making it suitable for a wide range of automation applications.

Vision350 PLCs are widely used by machine builders because they integrate PLC logic, HMI design, communications and data handling within one development environment. The controller can also be expanded with external modules, allowing systems to scale to larger automation architectures when required.
