Why Choose the Unitronics V120-22-R34 PLC with Integrated HMI?
The Unitronics V120-22-R34 is a powerful all-in-one Programmable Logic Controller (PLC) with integrated Human Machine Interface (HMI) designed for industrial automation, machine control and process monitoring applications. As part of the proven Unitronics Vision™ 120 series, it combines a graphic operator interface, onboard I/O, communication capabilities and advanced control functionality within a single compact platform.
Featuring a built-in 2.4-inch monochrome graphic LCD display and a durable 16-key keypad, the V120-22-R34 enables operators to monitor machine status, enter parameters and control processes without requiring a separate HMI terminal. This integrated approach reduces panel space, wiring complexity and overall system costs while maintaining excellent functionality.
With 20 digital inputs, 2 analogue inputs and 12 relay outputs, alongside dual RS232/RS485 communication ports and expansion capability, the V120-22-R34 is ideal for OEM machinery, packaging equipment, material handling systems and industrial automation projects requiring a versatile control solution.
