Honeywell UDC2500 Universal Digital Controller agent

The UDC2500 Universal Digital Controller is a new, low-priced addition to Honeywell’s Controller family. 

This controller introduces newfeatures in the popular low priced ? 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 TypesFigure 1 Front of UDC2500?2 Digital Inputs ? Ethernet and Modbus communication 

? Infrared PC & Pocket PC configuration 

? NEMA4X and IP66 front face protection ? Multilanguage prompts ? ? 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 ? 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 newconfiguration!

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 (every166 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 120seconds 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.
