Why Choose the Unitronics V120-22-UA2 PLC + HMI Controller?
The Unitronics V120-22-UA2 is a versatile programmable logic controller (PLC) with integrated HMI designed for machine automation, process control and industrial monitoring applications. As part of the proven Unitronics Vision120 series, this all-in-one controller combines advanced control logic, operator interface and onboard I/O within a single compact unit, helping reduce installation costs and control panel complexity.
By integrating a PLC and graphical HMI into one device, the V120-22-UA2 eliminates the need for separate control and display hardware. Engineers benefit from simplified wiring, easier commissioning and a streamlined automation architecture while operators gain access to real-time machine status, alarms and process information directly from the controller.
Featuring 10 digital inputs, 2 universal analogue inputs, 10 transistor outputs and 2 analogue outputs, the V120-22-UA2 provides excellent flexibility for both discrete and analogue control applications. Dual RS232/RS485 communication ports and expandable I/O capabilities make it suitable for standalone machines and larger automation systems alike.
