JZ20-J-T40 Unitronics Jazz Textual display and keybord HMI and PLC with upto 40 onboard I/Os

Why Choose the Unitronics JZ20-J-T40 PLC with Integrated HMI?

The Unitronics JZ20-J-T40 is a powerful micro PLC with integrated text HMI and keypad from the Unitronics Jazz series. Designed for compact machine control and automation systems, the controller combines PLC logic, operator interface and onboard I/O in a single device, reducing panel space and simplifying wiring.

Powered by a 24 V DC supply, the controller offers a high number of integrated I/O points including digital, analogue and high-speed inputs alongside multiple transistor outputs. This makes it suitable for controlling motors, valves, sensors and other automation devices without additional expansion modules.

The Jazz PLC platform supports Modbus communication and ladder logic programming using Unitronics U90 Ladder software, providing a cost-effective solution for OEM machine builders and industrial automation engineers.
