The Unitronics JZ20-J-R16 is a compact all-in-one PLC and HMI controller from the Unitronics Jazz series, designed for cost-effective control of small machines and industrial automation systems. Combining a programmable logic controller with a textual display and keypad interface, the unit enables operators to monitor processes, adjust parameters and control equipment directly from the front panel.

Powered by a 24 V DC supply, the controller integrates onboard digital and analogue inputs and relay outputs, making it suitable for a wide range of automation tasks without requiring additional modules. The Jazz platform also supports Modbus communication and free ladder programming software, enabling easy integration into industrial control systems.

With its integrated operator panel, built-in I/O and simple programming environment, the JZ20-J-R16 provides a powerful yet affordable solution for machine builders and system integrators needing compact automation control.
