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.

process control needs.
Analog Inputs
The UDC3200 has two analog inputs
with a typical accuracy of ±0.20% of fullscale 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.

Outputs and Control
Output Types - The UDC3200 may
have as many as five outputs made up
of the following types:
• Current Outputs (4-20 or 0-20 ma)
• Electromechanical Relays (5 amps)
• Solid State Relays (1 amp)
• Dual Electromechanical Relays (2
amps)
• Open Collector Outputs
Output Algorithms - The UDC3200 is
available with one or more of the
following output algorithms:
• Time Proportional provides On-Off
or Time Proportional (Relay) output.
• Current Proportional supplies
proportional direct current output for
final control elements, which require
a 4-20mA signal. Output can be
easily configured via the keyboard
for 0-20mA operation without
recalibration.
• Position Proportional—Positions a
reversible motor with a feedback
slidewire in proportion to the output
of the control algorithm. Requires
two output relays and the optional
second analog input.
• Current Proportional Duplex is
Similar to current proportional but
provides a second set of tuning
parameters and a split range current
output or a second current output
via the Auxiliary output option, for
the heat and cool zones.
• Time Proportional Duplex Depending on which control
algorithm you select, this duplex
output algorithm can provide On-Off
Duplex, Time Proportional Duplex,
or Three Position Step Control. The
time proportional duplex output
provides independent PID tuning
constants and two time proportional
outputs; one for heat zone above
50% output, and one for cool zone
below 50% output.
• Current/Relay Duplex
(Relay=Heat) - A variation of
Duplex with Current active for 0 to
50% output (PID Set 2) and Relay 2
active 50 to 100% output (PID Set
1). Note that only one alarm is
available for this output type.
• Relay/Current Duplex
(Relay=Cool) - A variation of
Duplex with Current active for 50 to
100% output and Relay 2 is active
for 0 to 50% output. Note that only
one alarm is available for this output
type.
Control Algorithms - Depending on the
output algorithms specified, the
controller can be configured for the
following control algorithms:
• On-Off
• PID-A
• PID-B
• PD with Manual Reset
• Three Position Step Control:
The TPSC algorithm allows the
control of a valve (or other actuator),
with an electric motor driven by two
controller output relays; one to move
the motor upscale, the other
downscale without a feedback
slidewire linked to the motor shaft.
Three Position Step is an automatic
back-up mode to Position
Proportional Control if the feedback
slidewire signal should fail
• 3 control modes: Manual, Automatic
with Local Setpoint, Automatic with
Remote Setpoint
Alarms
One or two electromechanical alarm
relays are available to activate external
equipment when preset alarm setpoints
are reached. Each of the two alarms
can be set to monitor two independent
setpoints. Each alarm setpoint can be
either high or low alarm. The alarm
type can be selected to be either of the
inputs, the Process Variable, Deviation,
Output, Shed from communications,
PV rate of change, or to alarm on
manual mode activation or a Current
Output Open failure. It can also be
used as an On or Off event at the
beginning or end of a Ramp/Soak
segment. The alarm hysteresis is
configurable from 0 to 100% of range.
• Alarms can be configured as
latching or non-latching.
• Alarm blocking is also available
which allows start-up without alarm
energized until after it first reaches
the operating region.
• PV rate of change alarm.
• Loop break alarm.
• Timer output reset.
• Diagnostic Alarm
Communication
A communications link is provided
between the UDC3200 and a host
computer or PLC via the RS422/485
Modbus® RTU or Ethernet TCP/IP
communications option. An infrared
communication link is also available
allowing a non-intrusive configuration
of the instrument.
Miscellaneous Features
Auxiliary Output* - Either or both of
the two current outputs can function as
an Auxiliary Output which can be
scaled from 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 30 volts dc to power a 2wire transmitter (it requires the use of
alarm 2 open collector output selection
or the second current output).
Three Local and one Remote
Setpoints - Can be configured to
provide three 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.
Miscellaneous Features (continued)
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 program and
store six Ramp and six Soak segments
for setpoint programming. 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 73/23/EEC,
Low Voltage Directive and 89/336/EEC,
the EMC Directive as a standard feature.
Approval Body Options - CSA
certification is available as an option. UL
listing is standard.
Two Sets of Tuning Constants - Two
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.
Quality/Support - The UDC3200 is
covered by an 18-month warranty and
backed up by a toll-free phone number
for technical assistance (US Only).
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 III
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.
Slowtune 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.
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.

• Ethernet (optional)
• Same port types on UDC2500 and UDC3500 allow
interconnectivity
• This software is available in English, Spanish, Italian,
German and French.
Infrared Communications
The infrared connection provides a non-intrusive wireless
connection with the instrument and maintains NEMA4X and
IP66 integrity.
No need to get access to the back of the controller to
communicate with the instrument, no need to take your
screw driver to wire the communication cable, no wiring
mistake possible! You can now duplicate an instrument’s
configuration, upload or download a new configuration in a
matter of seconds, just by pointing your Pocket PC in the
direction of the instrument.
Aim & Upload! It takes less than 2 seconds to upload a
configuration from an instrument! You can then save the
configuration file onto your PC or pocket PC for review,
modification or archiving.
Furthermore, this software also gives you important
maintenance information on the controller: instantly, get
information on the current operating parameters, digital
inputs and alarm status, identify internal or analog input
problems.
Question: What if I have several controllers on the same
panel? How can I be sure I am communicating with the
correct one?
Answer: The Infrared port is normally “off”. You activate the
infrared port on a particular controller by pressing any key.
You can now communicate with the controller. If no
communications are received for 4 minutes, the IR port will
be shut down again. Each controller may also be assigned a
different communications address.

Pocket PC
Ethernet Communications
Widely used by manufacturers, the Ethernet connection, which uses Modbus TCP/IP, allows the controller to connect to other
Ethernet networks and exchange data with computers or devices on that network for monitoring or managing your process
from almost any location.
The Ethernet cable can be connected to a hub (using a straight through cable) or directly to a PC (using a crossed cable or
straight through cable reconfigured at the UDC3200 terminals)
The controller can be configured via the PC software. This software allows the user to configure all of the parameters
included in the instrument and to monitor various parameters in the controller.
The controller can be configured to send an Email when an alarm condition has been encountered. The Email address and
gateway are configured using the PC software.
