February 12, 2009 – Unitronics' Jazz models offer a cost-effective solution for temperature control—a low-cost PLC with an embedded HMI and direct Temperature Measurement Inputs.The JZ10-11-UA24 offers 2 Thermocouple/PT100 inputs, 2 analog inputs and 2 analog outputs; JZ-11-UN20 offers 1 Thermocouple/PT100 inputs and 1 analog input. Both models include additional digital I/Os—total I/O count reaches up to 24 onboard I/Os.All Jazz models 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). Jazz also features 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 (yes, you can show the degree sign!). Jazz's control and communication options make it a big step up from any "smart-relay"—24K (virtual) of Ladder Logic enable flexibility and functionality. Software functions include interrupt, loops, math, store & compare. Communication options include SMS messaging, MODBUS networking and PC access via MODBUS or OPC. A Jazz PLC with onboard temperature inputs is an excellent solution for any small machine where "smart" temperature control is needed—ovens activated according to RTC, simple ramp & soak, simple multistep programmers etc.' It is also perfect for simple autoclaves, rotating tables, home automation, and other small-to-medium systems where every penny counts.
