Specification
Overview
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.

Figure 1 - UDC3000 Versa-Pro Controller
Dual Displays - Vacuum fluores-
cent alphanumeric displays and
indicators with dedicated PV
display.
Deviation Bargraph - “On Control”
indication or up to
±
10% deviation
display.
Easy Configuration - Multi-
language 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 II
TM
- 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 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.
