V120-22-R6C Unitronics V120-22 OPLC,6/6 IO,6 AN,CAN

Why Choose the Unitronics V120-22-R6C PLC with Integrated HMI?

The Unitronics V120-22-R6C is a compact PLC with an integrated HMI designed for industrial automation, machine control and process monitoring. As part of the reliable Unitronics Vision™ V120 series, this controller integrates PLC logic, operator interface and onboard I/O into a single device, helping reduce control panel complexity while maintaining powerful automation capabilities.

The controller includes a 2.4-inch monochrome graphic LCD display with a sealed membrane keypad, enabling operators to view system status, alarms and process values directly from the machine panel. Combining PLC and HMI functionality eliminates the need for a separate operator terminal and simplifies wiring and system architecture.

This model provides a versatile I/O configuration with 6 digital inputs, 6 analogue inputs and 6 relay outputs, allowing connection to sensors, transmitters, valves and other field devices. Integrated RS232 / RS485 serial ports and CANbus communication allow the controller to integrate with SCADA systems, drives and distributed automation networks.

The system can also be expanded with external modules, enabling the controller to scale to larger automation systems with significantly increased I/O capacity when required.
