April 1, 2013 - Unitronics introduces the JZ20-R31 programmable controller with 48K (virtual) Ladder Logic memory, 4 PID loops, built-in HMI, and a built-in mini USB programming port.
With the same look, dimensions, wiring and functional behavior, the JZ20-R31 model has complete backward compatibility as the standard Jazz. The JZ20-R31 is suitable for replacing ‘smart relays,’ for applications such as simple autoclaves, rotating tables, home automation, and other small-to-medium systems.
All controllers include 4 auto-tune PID loops. PID can be set using the onboard temperature/analog inputs, and the analog or PWM outputs; all onboard transistor outputs can function as PWM outputs. It has a full-function HMI with a two line LCD text display that shows up to 60 user-designed screens, and a 16-key keypad. The multilingual display supports over 15 languages, and 20 graphic symbols. With 48K (Virtual) of Ladder Logic, these units provide flexibility, functionality and power.
Software functions include: interrupt, loops, math, store and compare. Communications options include SMS messaging, MODBUS networking and PC access via MODBUS or OPC. Unitronics’ free software provides one user-friendly environment for hardware configuration, and HMI design. Unitronics also offers free technical support for all products. The new JZ20-R31 and Jazz 2 series reduces overall system costs by minimizing hardware requirements, saving cabinet space—and, above all—exempting the user from setting up Panel-PLC communication.
