Why Choose the Unitronics V350-35-TR6 Vision350 PLC + HMI?
The Unitronics V350-35-TR6 is a compact and highly capable PLC + HMI controller that combines advanced programmable logic control, integrated I/O and a vibrant 3.5-inch colour touchscreen within a single industrial automation platform. As part of the proven Vision350 series, it offers machine builders and automation engineers a flexible solution for machine control, process monitoring and operator interaction.
Designed to reduce panel space, simplify wiring and lower installation costs, the V350-35-TR6 integrates digital inputs, analogue inputs, relay outputs and high-speed transistor outputs into one controller. The colour touchscreen interface allows operators to monitor machine performance, acknowledge alarms and modify process settings through intuitive HMI screens.
With 8 configurable digital inputs, 4 analogue inputs, 6 relay outputs and 2 high-speed NPN transistor outputs, the V350-35-TR6 is ideal for industrial machinery, process automation, packaging systems and material handling applications. Expansion capability supports up to 512 I/O points for larger automation projects.
