Why Choose the Unitronics V350-35-R34 Vision PLC + HMI Controller?

The Unitronics V350-35-R34 is a versatile PLC and HMI controller from the Unitronics Vision series, combining machine control, operator interface and onboard I/O in a single compact device. Designed for industrial automation systems, it features a 3.5-inch colour touchscreen alongside integrated digital and analogue inputs and relay outputs, enabling engineers to build complete control solutions without separate PLC and HMI hardware.

The controller provides a powerful platform for machine automation, supporting ladder logic programming and graphical HMI design through the Unitronics VisiLogic software environment. Its integrated architecture helps reduce panel wiring, simplify system design and lower overall automation costs.

With built-in communication ports and support for I/O expansion modules via CANbus networks, the V350-35-R34 can scale to larger automation systems with up to 512 total I/O points, making it suitable for both standalone machines and distributed control systems.
