SM43-J-TA22 Unitronics Samba 4.3" colour touchscreen HMI and PLC with onboard I/O configurations

Why Choose the Unitronics SM43-J-TA22 PLC with Touchscreen HMI?

The Unitronics SM43-J-TA22 is a powerful PLC with integrated colour touchscreen HMI from the Unitronics Samba series, designed for compact industrial automation and machine control applications. Combining programmable logic control, operator interface and onboard I/O within a single device, it simplifies system architecture while reducing wiring and installation time.

The controller features a 4.3-inch TFT colour touchscreen that enables operators to monitor machine status, adjust parameters and interact with automation processes directly from the panel. With integrated digital, analogue and temperature inputs together with transistor and analogue outputs, the SM43-J-TA22 can connect directly to sensors, actuators and process signals without requiring external expansion modules.

Powered by a 24 V DC supply, the controller supports ladder logic programming and HMI development using Unitronics’ Visilogic software, enabling engineers to design machine control logic and graphical interfaces within a single development environment.
