Specification
Overview
The UDC2500 Universal Digital
Controller is a new, low-priced addition
to Honeywell’s Controller 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 2300.
The UDC2500 monitors and controls
temperatures and other variables in
applications such as:
• furnaces and ovens,
• environmental chambers,
• packaging machinery,
• plastic processing machines.
Features
• 1 Universal Input + 1 high level
input
• 0.25% Accuracy
•
Fast scanning rate (166ms)
• Up to 5 Analog or Digital Output
Types
Figure 1 Front of UDC2500
• 2 Digital Inputs
• 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
• Downward compatibility with
existing UDC2300 applications
• Limit model
The standard features include
Accutune III™ 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 UDC2500 provides a ¼ DIN sized
alternative for many applications. Its
features include: Universal AC power
supply, optional RS422/485 Modbus
®
RTU or Ethernet 10Base-T TCP/IP
communication protocols, input/output
isolation, Isolated Auxiliary Current
output.
When these are combined with the
Accutune III™ tuning with fuzzy logic
overshoot suppression, the result is
price/performance leadership.
Configuration can be done with a PC
through communication or with a
Pocket PC, using the embedded infra
red communication port. No need to
get access to the back of the controller
to download or upload a brand new
configuration!
For the many thousands of satisfied
UDC2300 users, the UDC2500 is
downward-compatible with most
existing UDC2300 applications.
Analog Inputs
The UDC2500 has two analog inputs
with a typical accuracy of ±0.25% 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 input is a low-level type which
accepts thermocouple, RTD, ma, mV,
and voltage types (See Table 1 on
page 10.).
The second input is a high level type
and can be used as a remote setpoint,
for data acquisition or as a parameter
to be alarmed on. This input accepts
ranges 0-5V, 1-5V, 0-2V, 0-20mA or 4-
20mA.
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.
All input types are configurable via the
keyboard, there are no internal
jumpers or switches. The two inputs
are isolated from all other inputs and
outputs, but not from each other.
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.
