JZ20-UA24 – Unitronics JAZZ,Di 2X16,15/9IO,AI/O,USB

Why Choose the Unitronics JZ20-UA24 Jazz PLC with Integrated HMI?

The Unitronics JZ20-UA24 is a versatile micro PLC with integrated textual HMI designed for compact industrial automation systems and OEM machinery. Part of the Unitronics Jazz™ series, this controller integrates PLC logic, operator interface and extensive onboard I/O within a single panel-mounted unit, reducing system complexity and eliminating the need for a separate HMI device.

The controller features a 2 × 16 character STN LCD display and a 16-key membrane keypad with user-programmable keys, allowing operators to monitor process data, adjust parameters and view alarms directly on the unit. This integrated PLC-HMI architecture provides a compact and cost-effective automation platform.

The JZ20-UA24 includes a flexible I/O configuration with 9 digital inputs, 2 configurable digital/analogue inputs, 4 analogue inputs, temperature inputs, relay and transistor outputs and analogue outputs. This combination enables the controller to handle sensors, actuators and analogue process signals in a wide range of industrial applications.

The controller operates from a 24 V DC power supply and is programmed using the free Unitronics U90™ Ladder development software, which allows engineers to design PLC logic and HMI screens within a single programming environment.
