V350-J-B1 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-B1 Vision PLC with Touchscreen HMI?

The Unitronics V350-J-B1 is a powerful programmable logic controller with an integrated touchscreen HMI designed for advanced industrial automation systems. Part of the reliable Unitronics Vision series, the controller combines PLC functionality with a graphical operator interface in a single compact device.

The controller features a 3.5-inch colour TFT touchscreen display with a resolution of 320 × 240 pixels, allowing operators to monitor processes, view alarms and interact with machines through intuitive graphical screens. The integrated design simplifies machine architecture by eliminating the need for a separate HMI panel.

Designed for flexible automation systems, the V350-J-B1 supports expansion modules that allow systems to scale up to hundreds of I/O points. The controller includes built-in communication interfaces such as RS-232 and RS-485 and supports optional communication modules including Ethernet, CANbus and Profibus.

The device operates from a 12 or 24 V DC power supply and is engineered for reliable operation in industrial environments. It is commonly used in machinery, process control and building automation applications requiring both PLC logic and operator interaction.

PLC and HMI Integration for Automation Systems

Modern automation systems require both control logic and operator interaction. Integrated controllers such as the Unitronics Vision series combine PLC control with a graphical interface, allowing operators to monitor processes, adjust parameters and respond to alarms directly from the machine interface.

This architecture reduces system complexity, lowers hardware costs and improves operator visibility across industrial equipment.

Typical Applications

• Industrial machine automation.
• Packaging and production equipment.
• Building automation systems.
• Water treatment and pump control.
• Process monitoring and industrial control panels.
