Why Choose the Unitronics JZ20-R10 Jazz PLC with Integrated HMI?

The Unitronics JZ20-R10 is a compact all-in-one micro PLC with integrated textual HMI designed for small automation systems and machine control. Part of the reliable Unitronics Jazz™ series, this controller combines PLC logic, operator interface and built-in I/O within a single panel-mounted device, simplifying automation design and reducing wiring complexity.

The controller features a 2 × 16 character LCD display and a 16-key keypad with programmable function keys, allowing operators to monitor machine status, adjust parameters and view alarms directly on the unit. This integrated design removes the need for a separate HMI while maintaining robust PLC functionality.

The JZ20-R10 includes 6 digital inputs (including 2 high-speed counter inputs) and 4 relay outputs, making it suitable for controlling sensors, switches, solenoids and relays in compact automation systems. Relay outputs are rated up to 5 A at 250 VAC or 24 VDC, providing reliable switching capability for industrial loads.

The controller runs on a 24 V DC power supply and includes battery-backed memory for retaining system data and real-time clock information. Programming is performed using the free Unitronics U90 Ladder software, which integrates ladder logic programming with HMI screen configuration.
