V120-22-UA2 Unitronics V120-22 OPLC,12/10IO,2/2 AN

Why Choose the Unitronics V120-22-UA2 PLC with Integrated HMI?

The Unitronics V120-22-UA2 is a compact PLC with integrated HMI designed for industrial automation, machine control and process monitoring. As part of the reliable Unitronics Vision™ V120 series, this all-in-one controller combines logic control, operator interface and versatile onboard I/O in a single panel-mounted device, reducing wiring complexity and saving valuable control cabinet space.

The controller features a 2.4-inch monochrome graphic LCD display with a sealed 16-key membrane keypad, allowing operators to monitor machine status, alarms and process data directly from the control panel. By integrating PLC and HMI functionality, the V120-22-UA2 eliminates the need for a separate operator panel while maintaining powerful automation capability.

This model offers a flexible mixed I/O configuration including digital inputs, transistor outputs and universal analogue inputs. The adaptable inputs can operate as analogue, digital or thermocouple measurement channels, making the controller suitable for both machine automation and process monitoring applications.

Integrated RS232 / RS485 communication ports allow the PLC to connect with SCADA systems, industrial devices and automation networks. The controller also supports I/O expansion modules, enabling systems to scale up to approximately 256 total I/O points when required.
