V120-22-UN2 Unitronics V120-22 OPLC,12/12IO,2 UNIV

Why Choose the Unitronics V120-22-UN2 PLC with Integrated HMI?

The Unitronics V120-22-UN2 is a compact PLC with integrated HMI designed for industrial automation, machine control and process monitoring. Part of the reliable Unitronics Vision™ V120 series, this all-in-one controller integrates logic control, operator interface and onboard I/O within a single panel-mounted device, simplifying control system design and reducing panel wiring.

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 values directly from the control panel. Combining PLC and HMI functionality eliminates the need for a separate operator interface while maintaining powerful automation capability.

The V120-22-UN2 provides a flexible I/O configuration including 10 digital inputs, 2 universal inputs and 12 transistor outputs. The universal inputs can be configured for analogue signals, thermocouple sensors, PT100 temperature sensors or digital inputs, providing excellent versatility for both machine automation and process control applications.

Integrated RS232 / RS485 communication ports allow the controller to communicate with SCADA systems, drives and industrial devices. The controller can also be expanded using external modules, enabling systems to scale up to approximately 256 total I/O points when required.
