Why Choose the Unitronics JZ20-T18 Jazz PLC with Integrated HMI?

The Unitronics JZ20-T18 is a compact micro PLC with integrated textual HMI designed for small to medium industrial automation systems. As part of the reliable Unitronics Jazz™ series, this controller integrates PLC logic, operator interface and built-in I/O into a single panel-mounted device, helping reduce system cost and wiring complexity while maintaining powerful automation capabilities.

The controller includes a 2 × 16 character LCD display and a 16-key keypad that allows operators to monitor machine status, change parameters and display alarms directly on the device. This integrated design removes the need for a separate HMI and provides an efficient automation solution for compact machinery and control panels.

The JZ20-T18 provides flexible onboard I/O including 6 digital inputs, 2 configurable digital/analogue inputs, 2 analogue inputs and 8 transistor outputs. Two of the digital inputs can function as high-speed counters capable of handling signals up to approximately 10 kHz, making the controller suitable for encoder, pulse and counting applications.

The controller operates from a 24 V DC power supply and is programmed using the free Unitronics U90™ Ladder software, which integrates ladder logic programming and HMI configuration within a single development environment.
