V120-22-T1 Unitronics V120-22 OPLC,12/12IO

Why Choose the Unitronics V120-22-T1 PLC with Integrated HMI?

The Unitronics V120-22-T1 is a compact PLC with integrated HMI designed for industrial automation and process control applications requiring accurate temperature measurement. As part of the reliable Unitronics Vision™ V120 series, this controller integrates PLC logic, operator interface and onboard I/O into a single panel-mounted unit, reducing wiring complexity and saving control cabinet space.

The controller features a 2.4-inch monochrome graphic LCD display with a sealed membrane keypad, allowing operators to monitor system status, alarms and process values directly from the machine panel. The integrated design removes the need for a separate operator interface while maintaining powerful automation functionality.

The V120-22-T1 is specifically designed for applications requiring temperature monitoring and control, featuring dedicated thermocouple inputs alongside digital and relay I/O. Integrated RS232 and RS485 communication ports enable connectivity with SCADA systems, industrial devices and distributed automation networks.

The controller also supports I/O expansion modules, enabling systems to scale up to approximately 256 total I/O points for larger automation systems.
