SM70-J-TA22 Unitronics Samba 7" colour touchscreen HMI and PLC with onboard I/O configurations

Why Choose the Unitronics SM70-J-TA22 PLC with Touchscreen HMI?

The Unitronics SM70-J-TA22 is a versatile PLC with integrated 7-inch colour touchscreen HMI from the Unitronics Samba series, designed for industrial automation, OEM machinery and process control systems. By combining programmable logic control, operator interface and onboard I/O within a single compact device, the controller reduces panel wiring complexity and simplifies machine design.

The unit features a 7″ high-resolution TFT colour touchscreen that enables operators to monitor processes, configure parameters and interact with equipment directly from the panel interface. Built-in digital, analogue and temperature inputs together with transistor and analogue outputs allow direct connection to sensors, actuators and process instruments without requiring additional expansion modules.

Powered by a 24 V DC supply, the SM70-J-TA22 supports ladder logic programming and HMI development using Unitronics’ VisiLogic software platform, allowing engineers to design machine logic, alarms and graphical operator screens within a single development environment.
