SM35-J-TA22 Unitronics Samba 3.5" colour touchscreen HMI and PLC with onboard I/O configurations

Why Choose the Unitronics SM35-J-TA22 PLC with Touchscreen HMI?

The Unitronics SM35-J-TA22 is a compact PLC with integrated colour touchscreen HMI from the Unitronics Samba series. Designed for machine builders and industrial automation engineers, it combines programmable logic control, a full-colour operator interface and integrated I/O in a single device, reducing panel space and simplifying machine wiring.

The controller features a 3.5-inch TFT colour touchscreen that enables operators to monitor process data, configure parameters and control equipment directly from the panel interface. With built-in digital, analogue and temperature inputs along with transistor and analogue outputs, the controller can connect directly to sensors, switches, valves and drives without requiring additional expansion modules.

Powered by a 24 V DC supply, the SM35-J-TA22 supports ladder logic programming and touchscreen HMI configuration within Unitronics’ integrated development environment, making it a practical and cost-effective automation platform for OEM machinery and industrial control applications.
