V350-J-R34 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-R34 Vision PLC with Touchscreen HMI?

The Unitronics V350-J-R34 is an advanced programmable logic controller with an integrated colour touchscreen HMI designed for industrial automation and machine control applications. Part of the powerful Unitronics Vision series, this device combines PLC control logic, operator interface and onboard I/O in a single compact controller.

The controller features a 3.5-inch colour TFT touchscreen display with a resolution of 320 × 240 pixels, enabling operators to monitor machine conditions, acknowledge alarms and interact with process controls through graphical HMI screens. The integrated PLC and HMI design simplifies system architecture and reduces the need for additional hardware in industrial control panels.

The V350-J-R34 includes a versatile built-in I/O configuration with 22 digital inputs, 2 analogue/digital inputs and 12 relay outputs, providing direct connectivity for sensors, actuators and automation devices. The controller can also be expanded using I/O modules, allowing systems to scale to hundreds of additional inputs and outputs for larger automation systems.

The controller operates from a 24 V DC power supply and supports industrial communication interfaces such as RS-232 and RS-485. Optional modules allow additional communication capabilities including Ethernet, CANbus and Profibus, making the V350-J-R34 suitable for integration into modern industrial networks.

Integrated PLC and HMI for Industrial Control

Industrial automation systems often require both control logic and an operator interface. Controllers such as the Unitronics Vision series integrate these functions into a single device, allowing operators to monitor machine conditions, adjust parameters and control processes directly from a touchscreen interface.

This integrated architecture reduces installation complexity, lowers hardware costs and improves reliability compared with separate PLC and HMI systems.

Typical Applications

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