JZ20-J-UA24 Unitronics Jazz Textual display and keybord HMI and PLC with upto 40 onboard I/Os

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

The Unitronics JZ20-J-UA24 is a compact micro PLC with integrated HMI and keypad from the Unitronics Jazz series, designed for reliable control of small machines and industrial automation systems. Combining PLC logic, a 2-line LCD operator display and a full set of onboard I/O in one device, it reduces wiring complexity and simplifies control panel design.

Powered by a 24 V DC supply, the controller offers a versatile mix of digital, analogue and temperature inputs along with relay, transistor and analogue outputs. This flexible configuration enables direct connection to sensors, actuators and process signals without requiring additional expansion modules.

The integrated keypad and display allow operators to monitor machine status, adjust settings and interact with the automation process directly from the front panel. With support for Modbus communication and ladder logic programming, the JZ20-J-UA24 is a practical and cost-effective automation solution for OEM machinery and compact control systems.
