V350-35-B1 Unitronics V350 OPLC,3.5" ,NO I/O

Why Choose the Unitronics V350-35-B1 Vision PLC + HMI Controller?

The Unitronics V350-35-B1 is an advanced all-in-one PLC and HMI controller from the Unitronics Vision series, designed for industrial automation systems that require both machine control and operator interface functionality in a single device. It combines a powerful programmable logic controller with a 3.5-inch colour touchscreen HMI, helping engineers reduce wiring, panel space and overall system complexity.

The controller features a 320 × 240 pixel colour TFT display with a resistive touchscreen and programmable function keys. Operators can monitor machine performance, view alarms and adjust process parameters directly through the interface. Using the Unitronics VisiLogic development environment, engineers can program ladder logic and design HMI screens within a single software platform.

The V350-35-B1 does not include onboard I/O but supports local and remote expansion modules via expansion ports and CANbus networks, allowing systems to scale up to 512 I/O points depending on configuration. This modular architecture enables flexible automation solutions for machines, production lines and process control systems.
