V350-J-RA22 Unitronics Vision 3.5" graphic display and keypad HMI and PLC onboard I/Os accepts I/O expansions up to 512 I/Os

Why Choose the Unitronics V350-J-RA22 Vision PLC with Integrated Touchscreen?

The Unitronics V350-J-RA22 is an advanced PLC with integrated colour touchscreen HMI from the Vision350 series, designed for industrial automation, machine control and OEM equipment. By combining PLC logic, graphical operator interface and onboard I/O within a single device, it simplifies control panel architecture while reducing wiring, hardware costs and installation time.

The controller features a 3.5-inch colour TFT touchscreen display that provides intuitive machine monitoring and operator interaction. Users can view process values, manage alarms and modify parameters directly through the graphical interface. The unit includes versatile onboard I/O supporting digital, analogue and temperature inputs together with relay and analogue outputs for flexible integration with industrial sensors and actuators.

Powered by a 24 V DC supply, the V350-J-RA22 supports industrial communication via RS-232 and RS-485 interfaces and can be expanded using Unitronics expansion modules to build larger automation systems with extensive I/O capability.
