V120-22-RA22 Unitronics V120-22 OPLC,12/10 IO, 2 UNIV

Why Choose the Unitronics V120-22-RA22 PLC with Integrated HMI?

The Unitronics V120-22-RA22 is an advanced PLC with integrated HMI designed for demanding industrial automation and process control applications. Part of the reliable Unitronics Vision™ V120 series, this compact controller integrates logic control, operator interface and versatile onboard I/O into a single panel-mounted unit, simplifying control system design while saving valuable cabinet space.

The controller features a 2.4-inch monochrome graphic LCD display with a sealed 16-key membrane keypad, enabling operators to monitor machine status, alarms and process values directly at the control panel. This integrated PLC + HMI architecture eliminates the need for a separate operator terminal and reduces wiring complexity in automation systems.

The V120-22-RA22 includes 12 digital inputs, 8 relay outputs and multiple analogue I/O channels, supporting sensors, transmitters and actuators in a wide range of industrial control tasks. The controller also includes 2 analogue outputs and adaptable inputs capable of temperature measurement using RTD or thermocouple sensors, making it particularly suitable for process control applications.

Integrated RS232 and RS485 serial communication ports allow connection to SCADA systems, industrial networks and field devices. The controller can also be expanded using external modules, supporting up to approximately 256 total I/O points for larger automation systems.
