Honeywell UDC2800 Universal Digital Controllers Series Micro-Pro Agent

New Power and Flexibility 

The UDC2800 Universal Digital Controller packs new powerful features in the popular 1/4 DIN size. Unmatched application power includes Bluetooth Configuration interface, two universal analog inputs and a Math Algorithm.  When these are combined with the Accutune III™ tuning with fuzzy logic overshoot suppression, the result is  price/performance leadership.  Application flexibility is assured by the universal analog inputs, universal AC power supply, two digital inputs, a maximum of  two analog inputs and four digital outputs, RS485 Modbus RTU or Ethernet 10/100M Base-T TCP/IP communication  protocols, simple configuration plus total field upgrade capability for any optional feature.

The key features of the UDC2800 include: 

• 2 Universal Analog Inputs 

• 0.15% Accuracy 

• Fast scanning rate (100ms) 

• Up to 4 Output Types 

• 2 Digital Inputs 

• Math Functions 

• Ethernet and Modbus communication 

• Bluetooth configuration on mobile device 

• NEMA4X and IP66 front face protection 

• Multilanguage prompts

• ¼ DIN Size 

• Jumper free configuration Bright displays with multi-language prompts in English, make the operator interface easy to read, understand, and  operate. Simple keystrokes let you set operating parameters that meet your process control needs.

Analog Inputs 

The UDC2800 has two analog inputs with a typical accuracy of ±0.15% of full-scale input and a typical resolution of 16 bits.  Both analog inputs are sampled ten times per second (every 100 ms).  The first, or Process Variable input, can be one of the various thermocouple, RTD, or linear actuations. Linear actuations  have thermocouple, RTD characterization capability as a standard feature. Linear actuations also have square root  capability. The optional second input is isolated and accepts the same actuations as input one. All actuations and characterizations are keyboard configurable. Cold junction compensation is provided for thermocouple  type inputs. Upscale, downscale or failsafe sensor break protection is keyboard configurable. A configurable digital filter of 0  to 120 seconds provides input signal damping.  

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.
