DR4500A Classic Series Circular Chart Recorder

Honeywell’s Classic Series recorder combines the simplicity of pen drawn analog traces with the sophistication of microprocessor controlled functions. This combination results in a user configurable recorder that is easily adapted to meet a variety of application requirements—from blast furnace to laboratory.

Features

• Charts — Over 5000 preprinted charts are available to meet specific recording needs.
• User configurable — means that users can set and/or alter operating parameters to fit their requirements, including type of input, without recalibration. English language prompts, coupled with simple keystroke sequences, make configuring the recorder easy and straightforward.
• Operator interface — includes clear, brilliant alphanumeric displays; indicators; deviation bargraph; and keypad for visual and tactile interaction.
• Ink cartridge — Disposable, fibertip ink cartridge for reliable recording with minimal maintenance.
• Control Output — up to two versatile PID digital controllers lets users configure the exact control action needed for their process.
• Alarms — Integral “soft” alarms are easily set by users to announce selected out-of-limit conditions.
• Setpoint Ramp — A single setpoint ramp is user programmable and is easily repeated and activated through the Run/Hold key.
• Setpoint Rate — lets you define a ramp rate applied to any local setpoint change. A separate upscale or downscale rate is configurable.
• Set Point Ramp/Soak Programming — Lets users program and store 18 ramp and 18 soak segments. Run or Hold of program is keyboard or remote switch selectable. For each control loop, you can build up to 6 profiles using any number of consecutive segments of the program. You can select a recovery mode for powerup.
• Accutune II™ — This standard feature provides a new, truly plug and play tuning algorithm, which will, at the touch of a button or through a digital input, accurately identify and tune any process including those with deadtime and integrating processes. This speeds up and simplifies start-up plus allows re-tuning at any setpoint.
• Fuzzy Logic — This standard feature uses fuzzy logic to suppress process variable overshoot due to SP changes or externally induced process disturbances. It operates independently from AccutuneII? tuning. It does not change the PID constants, but temporarily modifies the internal controller response to suppress overshoot. This allows more aggressive tuning to co-exist with smooth PV response. It can be enabled or disabled depending on the application or the control criteria.
