V120-22-R34 Unitronics V120 OPLC,2x16 DISPLAY, 22/12IO

Why Choose the Unitronics V120-22-R34 PLC with Integrated HMI?

The Unitronics V120-22-R34 is a compact PLC with integrated HMI designed for industrial automation, machine control and process monitoring applications. As part of the robust Unitronics Vision™ V120 series, this all-in-one controller integrates PLC logic control, operator interface and onboard I/O in a single compact unit, reducing panel complexity and simplifying system architecture.

The controller features a 2.4-inch monochrome graphic LCD display with a sealed membrane keypad, allowing operators to monitor system status, alarms and machine parameters directly from the control panel. By combining PLC and HMI functionality, the V120-22-R34 removes the need for a separate operator terminal while maintaining powerful automation capabilities.

This model provides 12 digital inputs, 2 analogue inputs and 8 relay outputs, making it suitable for controlling motors, valves, sensors and other field devices. Integrated RS232 / RS485 serial communication ports and CANbus connectivity enable the controller to communicate with SCADA systems, drives, distributed I/O and industrial networks.

The system also supports I/O expansion modules, allowing installations to scale up to approximately 256 total I/O points when required for larger automation systems.
