Honeywell UDC3500 1/4 DIN, High Accuracy, 2-Loop Universal Controller

1/4 DIN, High Accuracy, 2-Loop Universal Controller

New Power and Flexibility The UDC3500 Universal Digital Controller packs new powerful features in the popular 1/4 DIN size. Unmatched application power includes: Infrared (IR) Configuration interface, three universal analog inputs, two loops of control and two Math Algorithms. 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, four digital inputs, a maximum of seven analog and digital outputs, Infrared, RS422/485 Modbus RTU or Ethernet 10Base-T TCP/IP Modbus communication protocols, simple configuration plus total field upgrade capability for any optional feature.

• 3 Universal Analog Inputs (can be configured to operate as 1 Universal and 4 High Level Inputs)
• 0.10% Accuracy
• Fast scanning rate (166ms)
• Up to 3 Analog Outputs
• Up to 5 Digital Outputs
• 4 Digital Inputs
• Math Functions
• Ethernet or RS-485 communication
• Cascade or 2 Loops of control
• Infrared PC & Pocket PC configuration
• Healthwatch Maintenance Tool
• NEMA4X and IP66 front face protection
• Multilanguage prompts
• ¼ DIN Size
• Easily Field Upgradeable
• Bright, dual displays with multi-language prompts (in English, French, German, Spanish, or Italian) make the operator interface easy to read, understand, and operate. Simple keystrokes let you set operating parameters that meet your process control needs.

Digital Inputs (Four) (Optional) +30 Vdc source for external dry contacts or isolated solid state contacts. Digital Inputs are isolated from line power, earth ground, analog inputs and all outputs.
Current and Auxiliary
Up to three Milliamp Outputs. These outputs provide a 0 to 21 mA current output into a negative or positive grounded load or into a non-grounded load. Current outputs are isolated from each other, line power, earth ground and all inputs. Outputs can easily be configured via the keyboard to be 0 to 20 mA or 4 to 20 mA without field calibration and for either direct or reverse action when used as a control output.

Any current output not being used as a control output can be used in an Auxiliary Output mode. Auxiliary Outputs can be configured to represent any Analog Input, PV, Setpoint, Deviation, or Control Output. The range of an Auxiliary Output can be scaled per the range of the selected variable and can be set anywhere between 0 to 21 mA.
    Resolution: 14 bits over 0 to 21 mA
    Accuracy: 0.05% of full scale
    Temperature Stability: 0.01% F.S./°C
    Load Resistance: 0 to 1000 ohms

The First Current Output is a standard feature and is present on all instruments. The Second Current Output is an option and is mutually exclusive with Ethernet Communications. The Third Current Output is an option and is mutually exclusive with the other Output 2 Options listed directly below.

Power Consumption 24 VA maximum (90 to 264 Vac)
