Honeywell UDC2500 Universal Digital Controller inventory

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 ?  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  

? ? 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 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.
