V120-22-R1 Unitronics V120-22 OPLC ,10/6 IO,1 ANA

Why Choose the Unitronics V120-22-R1 PLC with Integrated HMI?

The Unitronics V120-22-R1 is a compact programmable logic controller with an integrated operator interface from the Unitronics Vision™ series. The controller combines PLC functionality, onboard I/O and a graphic HMI display within a single device, reducing wiring complexity and panel space requirements in industrial automation systems.

The controller includes a 2.4-inch monochrome LCD display with a keypad interface that allows operators to monitor machine status, alarms and process parameters directly from the controller panel. This integrated design enables engineers to build efficient automation solutions without requiring a separate HMI unit.

With 10 digital inputs, 1 analogue input and 6 relay outputs, the V120-22-R1 offers flexible control capability for a wide range of industrial applications. The controller also supports expansion modules allowing systems to scale up to approximately 256 total I/O points, making it suitable for both small and medium automation projects.
