£631.75
The Unitronics V350-35-TR34 is a feature-rich PLC + HMI controller that combines advanced programmable logic control, integrated I/O and a vibrant 3.5-inch colour touchscreen within a single compact automation platform. As part of the proven Vision350 series, it is designed to provide machine builders and automation engineers with a powerful solution for machine control, monitoring and operator interaction.
The controller integrates digital inputs, analogue input capability, relay outputs and high-speed transistor outputs while maintaining a compact footprint. By combining PLC functionality and an operator interface into one device, the V350-35-TR34 reduces panel space requirements, simplifies wiring and lowers overall installation costs.
With 22 onboard inputs, configurable analogue and high-speed encoder functionality, 8 relay outputs and 4 high-speed NPN transistor outputs, the V350-35-TR34 is ideal for industrial machinery, packaging systems, conveyor applications and OEM automation equipment. The controller also supports expansion up to 512 I/O points using Unitronics expansion modules.
The Unitronics V350-35-TR34 offers a unique combination of relay outputs and high-speed transistor outputs within a single controller. Relay outputs provide reliable switching for contactors, solenoids and general-purpose loads, while the transistor outputs support pulse generation, PWM control and motion-related applications requiring rapid switching speeds.
Its configurable inputs support standard digital signals, analogue measurements and encoder feedback, making the controller suitable for a wide variety of industrial automation projects. The integrated colour touchscreen further enhances usability by providing intuitive access to machine status, alarms, recipes and process information.
