COMMUNICATION
A communications link is provided between the UDC2800 and a host computer or PLC via the RS485 Modbus® RTU or Ethernet TCP/IP communications option. A Bluetooth communication link is also available allowing a non-intrusive configuration of the instrument.
MISCELLANEOUS FEATURES
Auxiliary Output* - Either or both two current outputs can function as an Auxiliary Output which can be scaled from 0-20 mA or 4-20 mA for 0 to 100% for any range. It can be configured to represent Input 1, Input 2, PV, active Setpoint, Local SP1, Deviation, or the Control Output.
Transmitter Power - This output provides up to 28 volts DC to power a 2-wire transmit¬ter (it requires the use of Open Collector Output (Transmitter Power Output) selection or the Auxiliary Output).
Four Local and one Remote Setpoints - Can be configured to provide Four Local and one Remote Setpoints, which are selectable either via the keyboard or by Digital Input.
Universal Switching Power - Operates on any line voltage from 90 to 264 Vac 50/60 Hz without jumpers. 24 Vac/dc instrument power is available as an option.
Timer - This standard feature provides a configurable time period of 0 to 99 hours, 59 minutes or units of minutes and seconds. It can be started via the keyboard, alarm 2, or by a digital input. The timer output is Alarm 1, which energizes at the end of the Timer Period. Alarm 1 can be automatically reset. The Timer Period can be changed between each batch. Status is shown on the lower display.
Moisture Protection - The NEMA4X and IP66 rated front face permits use in applications where it may be subjected to moisture, dust, or hose-down conditions.
Setpoint Ramp/Soak Programming (Optional) - Enables you to use 8 programs and store 4 Ramp and 4 Soak segments per program. Programs can be linked up to 64 segments. Run or Hold of program is keyboard or remote digital switch selectable.
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.
CE Mark - Conformity with Radio Equipment Directive 2014/53/EU as a standard feature.
Radio Compliance information -Federal Communications Commission (FCC) contains FCC ID: 2AVFQ-MCUDISP Industry Canada (IC) contains IC: 25762-MCUDISP
Approval Body Options - CSA/UL listed certification are available as an option. CE/FCC/IC is standard.Four Sets of Tuning Constants - Four sets of PID parameters can be configured for each loop and automatically or keyboard selected.
Data Security - Five levels of keyboard security protect tuning, configuration, and calibration data, accessed by a configurable 4-digit code. Nonvolatile EEPROM memory assures data integrity during loss of power.
Diagnostic/Failsafe Outputs - Continuous diagnostic routines detect failure modes, trigger a failsafe output value and identify the failure to minimize troubleshooting time.
High Noise Immunity - The controller is designed to provide reliable, error-free performance in industrial environments that often affect highly noise-sensitive digital equipment.
Accutune III™ - This standard feature provides a 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 retuning at any setpoint. The algorithm used is an improved version of the Accutune IIITM algorithm. Two possibilities are now offered when tuning your process: Fast Tune and Slow Tune.
Fast Tune will tune the process in such a way that the temp is reached faster, a slight overshoot will be allowed.
Slow Tune will minimize overshoot, but it will take more time for the process temperature to reach the target setpoint.
Heat/Cool (Duplex Tune) will automatically tune both the heating and cooling sides of the process.
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 Accutune III™ 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.
OPERATOR INTERFACE
Indicators-Provide alarm, control mode, and temperature unit indication. There is also indication of when Remote Setpoint is active, the status of the control relays, and whether a setpoint program is in Run or Hold mode.
Displays- TFT screen is adopted for better display. During normal operation, the upper and middle display is dedicated to the process vari¬able and setpoint variable and special annunciator features. During configuration, the upper, middle and lower display provides guidance for the operator through prompts.
During normal operation the lower display shows key-selected operat¬ing parameters such as Output, Setpoints, Inputs, Deviation, active Tuning Parameter Set, Timer Status, or minutes remaining in a setpoint ramp. During configuration, the lower display provides guidance for the operator through prompts. Diagnostic messages are displayed independently. Barchart of PV, SP, OUT displayed on screen.
You decide how the controller is to interact with the process by selecting, through simple keystrokes, the functions you want.
English prompts guide the operator step-by-step through the configuration process assuring quick and accurate entry of all configurable parameters.
Decimal Point Location-Configurable for none, one, two or three places.
Dedicated Keys-Provide direct access setpoint modes and setpoint program status to simplify and speed operation.
Universal Outputs - UDC2800 provides "out of the box" operations, with no need to open the case. There are no jumpers to connect, no switches to set, and no hardware configuration required.
