RAMPTROL

This microprocessor-based ramping control provides four-file/24-step program capability or easy-to-use non-ramping set-point operation. Ramping operations include four files with six steps each. Programming options include ramp-rate or time-based profiles, guaranteed soak deviation, program looping, and program status selection after power outage. Files may be linked to create a single, 24-step program. Also allows automatic setting of control parameters with little user input. RampTrol automatically sets the PID parameters (proportional band, reset/integral, and rate/derivative) through a “learning” sequence in the auto-tuning mode. The primary analog input is a thermocouple. The back panel features a nine-pin serial port for communication with a PC. A secondary output is available for cooling, along with a 4-20ma retransmit output for temperature recording and an RTD input. Information is stored in non-volatile memory.
