UDC2500 High Limit Controller by Honeywell

Only %1 left
Item Code: DC2500
  • The UDC2500 is being phased out. We have a number of configurations in stock. Please call and we can provide your options. 

 

  • The UDC2500 is being replaced with the UDC2800 model. The new model is completely backword compatable with the UDC2500.

 

  • Honeywell's UDC2500 1/4 DIN sized digital controller monitors and manages temperature and other variables in furnaces and ovens, environmental chambers, packaging machinery, and plastic processing machines. It's the upgrade to Honeywell's retired UDC2000 and UDC2300 models.

    Standard features on the UDC2500 include Honeywell Accutune III automatic tuning, fuzzy logic overshoot suppression, thermocouple health (drift) alarming, cold junction compensation on thermocouple inputs, upscale/downscale sensor break protection. RS485 Modbus RTU or Ethernet communications optional. The UDC2500 can be configured using the front-face pushbuttons, through the IR port, or using Process Instrument Explorer PC software.

    During normal operation, the UDC2500's upper display is dedicated to the process variable, and the lower display shows key operating parameters (output, setpoints, inputs, deviation, tuning parameter set, timer status, or minutes remaining in a setpoint ramp). Other indicators on the display show alarm, control mode, temperature unit indication, status of control relays, whether setpoint program is in run or hold mode.

    • Two analog inputs sampled 6 times per second; One for thermocouple, RTD, mA, mV, or voltage. Second optional high level for 0/1-5V, 0-2V, 0/4-20 mA
    • Accuracy ±0.25% full scale input, typical resolution 16 bits
    • Two digital inputs or one 4-20 mA auxiliary output and one digital input
    • Control output plus alarms: 0/4-20 mA, 5-amp electromechanical relay, 1-amp solid state relay, dual 2-amp electromechanical relays
    • Ramp/soak setpoint programming optional
    • Optional auto/manual mode
    • Optional Modbus RTU over RS-485 or Ethernet communications options
    • PID or On/Off, Heat/Cool, ratio, actuator three-position step control, manual bypass or feed-forward control modes
    • CE, UL, CSA approvals available, FM approved limit controller
    • Controller ships with mounting brackets, four screws for the NEMA 4 faceplate, and a printed quick-start guide
