Product Description
Honeywell UDC3000 Versa-Pro Universal Digital Limit Controller, DC300K-E-1A0-20-0000-0
PN: DC300K-E-1A0-20-0000-0
The UDC3000 Universal Digital Controller is Honeywell’s general purpose microprocessor-based, stand alone digital controller. It combines the highest degree of functionality and operating sim- plicity offered in a 1/4 DIN size. The bright dual displays with multi- language prompts make the operator interface easy to read, understand, and operate. Programmed sequences of dis- plays assure quick and accurate entry of all configurable parame- ters. Simple keystrokes let you select input and range configura- tion, set the operating parameters that meet your process control needs now, and change them later to meet new ones.
Dual Displays - Vacuum fluorescent alphanumeric displays and indicators with dedicated PV display. Deviation Bargraph - “On Control” indication or up to ± 10% deviation display. Easy Configuration - Multilanguage prompts, in programmed sequence, provide guidance during configuration. Individual, reliable tactile keys provide positive operator feedback. There are no internal jumpers to set. Universal Isolated Input - Input 1 accepts 10 thermocouple types, RTDs, Radiamatic RHs, mA, mV or voltage inputs through keyboard configuration. It is isolated from Input 2 and all other circuits. (See Table 1.) Thermocouple Failsafe - Configurable upscale or downscale burnout and failsafe output level. Decimal Point Location - Configurable for none, one, or two places.
Accutune IITM - 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 speedsup and simplifies startup plus allows retuning at any setpoint. Also included is the original Accutune SP Adaptive tuning that can automatically retune whenever a SP step change is implemented.
Fuzzy Logic - This new feature uses fuzzy logic to suppress process variable overshoot due to SP changes or externally induced process disturbance. It operates independently from Accutune 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.
Manual/Automatic Modes - Bumpless, balanceless transfer between control modes.
Two Local Setpoints - Can be configured to provide two local setpoints, keyboard or optional remote switch selectable.
Universal Switching Power - Operates on any line voltage from 90 to 264 Vac 50/60 Hz without jumpers. 24V ac/dc instrument power available as an option.
Limit Control - provides a latching relay which is activated whenever the PV goes above or below a preset setpoint value. An alarm indicator will light when the output is activated. Reset is through a key on the front of the controller or an external switch.
Setpoint Rate - Lets you define a ramp rate to be applied to any local setpoint change. A separate upscale or downscale rate is configurable. A single setpoint ramp is also available as an alternative.
