Universal Digital Controller
Overview
The UDC 2300 Universal Digital
Controller is a new low priced
addition to Honeywell’s LeaderLine
family.
This controller introduces new
features in the popular low priced
¼ DIN size while retaining all the
reliability, cost effectiveness,
simplicity, and popular HMI of
Honeywell’s UDC 2000.
The UDC 2300 monitors and controls
temperatures and other variables in
applications such as environmental
chambers, plastic processing
machines, furnaces and ovens, and
packaging machinery. The standard
features include AccutuneII™ and the
popular single display, automatic
mode model. A Dual Display model
with Automatic/Manual control modes
is optional. A Limit Control model is
also available.
The UDC 2300 provides a low priced,
1/4 DIN sized alternative for many
applications. Its new features
include:
Universal AC power supply,
RS485 ASCII or Modbus RTU
communications option,
Input/Output isolation, and
Isolated Auxiliary Current
output.
These features when combined with
the new AccutuneII tuning with
Fuzzy Logic overshoot suppression,
result in price/performance
leadership in the performance
segment positioned below the
UDC 3300 Controller.
For the many thousands of satisfied
UDC 2000 users, UDC 2300 is
downward compatible with existing
UDC 2000 applications and
installations. It even uses the same
case; therefore, it can be easily
inserted into existing panel
installations.
Modbus is a trademark of AEG Modicon

hosedown applications
Features/Options
High Accuracy
full scale input with a typical resolution
of 15 bits.
Analog Inputs
available. The first input accepts all
thermocouple, RTD, mA, mV, and
voltage types (See Table 1.).
Alternatively, the second input is a
high level input and can be used as a
remote setpoint, for data acquisition, a
parameter to be alarmed on. All input
types are configurable. All inputs are
sampled six times per second (every
166 ms). These two inputs are
isolated from all other inputs and
outputs, but not from each other.
Dual Setpoints -
selection allows quick switchover from
primary to alternate setpoint with
minimal operator confusion.
Manual/Automatic Modes
Bumpless, balanceless transfer
between control modes. Available with
a Dual Display option and SP
Programming option.

Features/Options, continued
Accutune II™
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 retuning at any setpoint.
Fuzzy Logic
uses fuzzy log ic 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.

Physical Description
The controller is housed in a 4.2-inch
deep, black metal case with a dark
gray elastomer bezel, that can be
panel mounted in a 1/4 DIN cutout.
(See Figure 5.) The plug-in chassis
allows easy access to the controller
board and its various option boards.
All power, input, and output wiring are
connected to screw terminals on the
rear panel. (See Figure 6.) Blue and
tan elastomer bezels are optionally
available.

Configuration
You decide how the controller is to
interact with the process by
selecting, through simple keystrokes,
the functions you want.
Multi-language prompts guide the
operator step-by-step through
configuration process assuring quick
and accurate entry of all configurable
parameters. Five languages are
available via configuration: English,
French, German, Spanish and
Italian.
the
Inputs
The analog inputs are sampled six
times a second.
The UDC 2300 is available with one
or two inputs. The first input, 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.
The optional second input is a high
level input and accepts ranges of
0-5V, 1-5V, 0-20mA, or 4-20mA.
All actuations and characterizations
are keyboard configurable. Cold
junction compensation is provided for
thermocouple type inputs. Upscale or
downscale sensor break protection is
keyboard configurable. A configurable
digital filter of 0 to 120 seconds
provides input signal damping.
Output Types
The following output types are
available per the model selection
guide:
• Current Output
• Electromechanical Relays (5
amps)
• Solid State Relays (1 amp)
• Solid State Relays (10 amps)
externally mounted (optional)
• Open Collector Outputs
• Auxiliary Current Output (optional)
Output Algorithms
The UDC 2300 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
4-20 mA signal.
Current Proportional Duplex—
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 the 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
to100% output (PID Set 1). Note that
only one alarm is available.
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. Not that only one alarm is
available.
Universal Output Model—Flexibility
of the output algorithms allows the
current output with two alarms model
(DC230B-CE) to also be configured
for current simplex, current duplex,
and time simplex. A relay output
model with auxiliary output option
(DC230B-CE-2) can also be
configured for these output
algorithms. Note that only current
simplex and current duplex can have
2 alarms.
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 Three Position Step Control
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.
Control Modes
The controller is capable of operating
in three different control modes:
1. Manual
2. Automatic with Local Setpoint
3. Automatic with Remote Setpoint
The manual and automatic control
modes with local and remote setpoint,
and bumpless, balanceless transfer
between modes.
Alarms
Alarm output terminals are located at
the rear terminal panel. 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. 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.
Configurable alarm features include:
•Alarm latching or non-latching
•Alarm blocking
•PV rate of change alarm
•Loop break alarm (Future)
•Timer reset
