Honeywell UDC3200 Universal Digital Controller

Overview

New Power and Flexibility

The UDC3200 Universal Digital Controller packs new powerful features

in the popular 1/4 DIN size.

Unmatched application power includes:

Infrared (IR) Configuration interface,two universal analog inputs and

a Math Algorithm. When these are combined with the Accutune III™

tuning with fuzzy logic overshoot suppression, the result is price/

performance leadership.

Application flexibility is assured by the universal analog inputs, universal

AC power supply, two digital inputs, a maximum of five analog and digital

outputs, RS422/485 Modbus RTU or Ethernet 10Base-T TCP/IP

communication protocols, simple configuration plus total field upgrade

capability for any optional feature.

Features

• 2 Universal Analog Inputs

• 0.20% Accuracy

• Fast scanning rate (166ms)

• Up to 5 Output Types

• 2 Digital Inputs

• Math Functions

• Ethernet and Modbus communication

• Infrared PC & Pocket PC configuration

• NEMA4X and IP66 front face protection

• Multilanguage prompts

• ¼ DIN Size

• Jumper free configuration

• Easily Field Upgradable

Bright, dual displays with multi-language prompts (in English, French,

German, Spanish, or Italian) make the operator interface easy to read,

understand, and operate. Simple keystrokes let you set operating

parameters that meet your process control needs.

Analog Inputs

The UDC3200 has two analog inputs with a typical accuracy of ±0.20%

of full scale input and a typical resolution of 16 bits.  Both analog inputs

are sampled six times per second (every 166 ms).

The first, or Process Variable input, can be one of the various thermocouple,

RTD, Radiamatic or linear actuations. Linear actuations have thermocouple,

RTD, and Radiamatic transmitter characterization capability as a standard

feature. Linear actuations also have square root capability.

The optional second input is isolated and accepts the same actuations as

input one, or it provides the Slidewire input for Position Proportional control.

All actuations and characterizations are keyboard configurable.

Cold junction compensation is provided for thermocouple type inputs.

Upscale, downscale or failsafe sensor break protection is keyboard configurable.

A configurable digital filter of 0 to 120 seconds provides input signal damping.

Thermocouple Health - In addition to the standard configurable upscale, downscale

or failsafe output burnout selections, the condition of the thermocouple can be

monitored to determine if it is good, failing or in danger of imminent failure.

Math Functions

Algorithm—A pre-configured algorithm is available for easy implementation.

This includes the capability of using a Ratio and Bias with any input.

You can select from the following menu:

Feedforward Summer—Uses either input, followed by a Ratio/Bias calculation,

summed directly with the computed PID output value to provide a resultant

output to the final control element (standard feature).

Weighted Average —Computes the weighted average of a PV or SP for

the control algorithm from two inputs (standard feature).

Feedforward Multiplier—Uses any input, multiplied by the calculated PID

output to provide a resultant output which is sent to the final control

element (standard feature).

Summer/Subtractor—Will add or subtract inputs with the result used as

the derived PV.

Multiplier/Divider—Uses the analog inputs to calculate a derived PV.

Available with or without Square Root.

Input High/Low Select—Specifies the PV input as the higher or lower of

the two inputs.

Digital Inputs

Two* isolated digital inputs are provided for remote dry contact closure

to select one of the following actions:

• Manual control mode.

• Local setpoint 1.

• Local setpoint 2.

• Local setpoint 3.

• Direct controller action.

• Hold SP Ramp/Program.

• Select PID set 2.

• PV = Input 2.

• ReRun - SP Ramp/Program.

• Run - SP Ramp/Program.

• External program reset.

• Disable PID integral action.

• Manual mode, failsafe output.

• Disable keyboard.

• Purge

• Low Fire

• To Latching Manual Mode.

Also, the digital inputs can allow one of the following selections to be

combined with one of the above selections:

• Select PID set 2.

• Direct controller action.

• Local setpoint 2 or Local setpoint 1.

• Disable Accutune

• To Run – SP Ramp/Program

*The 2nd Current Output and the 2nd Digital Input are mutually exclusive.

Selection is made via a keyboard entry.
