Honeywell UDC2500 Universal Digital Controller

• Furnaces and ovens
• Environmental chambers
• Packaging machinery
• Plastic processing machines

Features:

• 1 Universal Input + 1 high level input
• Up to 5 Analog or Digital Output Types
• Ethernet and Modbus communication
• Infrared PC & Pocket PC configuration
• NEMA4X and IP66 front face protection
• Multilanguage prompts
• Jumper free configuration
• Easily Field Upgradable
• Downward compatibility with existing UDC2300 applications
• Limit model

• The standard features include Accutune IIITM 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 1-4 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 IIITM 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 (every166 ms)
• The first input is a low-level type which accepts thermocouple, RTD, ma, mV and voltage types
• 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.

Communications:

• A communications link is provided between the UDC2500 and a host computer or PLC via the RS422/485
• Modbus® RTU or Ethernet TCP/IP communications option.
• An infrared communication link is also available allowing a non-intrusive configuration of the instrument.
