£322.00
The Unitronics SM43-J-T20 is a compact and powerful PLC with integrated colour touchscreen HMI designed for industrial automation, machine control and OEM applications. As part of the advanced Unitronics Samba series, it combines a programmable logic controller, operator interface and onboard I/O into a single platform, reducing hardware requirements, simplifying installation and lowering overall project costs.
Designed for machine builders, automation engineers and control panel manufacturers, the SM43-J-T20 delivers reliable PLC performance alongside a high-resolution 4.3-inch TFT colour touchscreen display. Its integrated architecture enables both PLC logic and HMI development within a single software environment, helping reduce engineering time while simplifying commissioning and maintenance.
Featuring 12 digital inputs, 2 analogue inputs and 8 transistor outputs, the SM43-J-T20 is ideally suited for packaging machinery, conveyor systems, pumping stations, HVAC equipment and industrial process control applications. Operating from a 24 VDC power supply, it provides a cost-effective automation solution with support for optional industrial communication modules.
The SM43-J-T20 combines PLC functionality and touchscreen operator control within a single automation platform. This integrated design reduces hardware costs while providing operators with real-time access to machine status, alarms, production data and process parameters.
Using Unitronics VisiLogic software, engineers can create both PLC applications and HMI screens within a unified development environment. Advanced functionality includes data logging, PID control, alarm management, recipe handling and communication with external devices, making the controller suitable for a wide range of industrial applications.
