Libratherm manufactures Six Zone Microcontroller based Multiple Ramp/Soak programmable PID/On-Off Temperature Controller cum Profile Programmer Model PRC-6000 which is designed to improve reliability, accuracy, and control of six independent heating zones. It features Ramp and Soak functions (the capability to control the temperature and its rate of change over a predetermined time span). A single and common pattern of 4 ramp/soak steps – (Fixed pattern of 1st pre-heating ramp, 2nd heating ramp, 3rd soaking, and 4th cooling ramp) for all six zones or each of the six-zone can be independently programmed and stored in the memory. This Multi-Channel PID Profile Controller PRC-6000 can also be used as single set point control when the ramp/soak profile control is not desired. PID SSR Programmer PRC-6000 accepts six K type thermocouples and provides outputs in the form of 6 relay contacts in PID or ON/OFF control mode. An extra relay contact is provided to indicate the thermocouple fault condition.
