Main Product Information
Brand: Honeywell
Model: UDC2800
Product Type: Universal Digital Limit Controller
Size: 1/4 DIN panel-mounted controller
Input: 1 universal analog input
Accuracy: +/-0.15% of full scale typical
Sampling Rate: 100 ms
Communication: Bluetooth standard, RS485 Modbus RTU or Ethernet TCP/IP optional
Key Features
The Honeywell UDC2800 provides one universal analog input for thermocouple, RTD and linear input actuations. The input has typical 16-bit resolution and is sampled ten times per second for fast process response.
Application flexibility is supported by universal AC power supply, digital input, up to four output types and simple field upgrade capability for optional features.
The front face can support NEMA4X and IP66 protection when correctly installed, making it suitable for industrial panels where moisture, dust or hose-down conditions may be present.
Inputs, Outputs and Alarms
The UDC2800 supports current outputs, open collector outputs and electromechanical relays depending on configuration. Current outputs can be configured as 0-20 mA or 4-20 mA, and can also function as auxiliary output.
One isolated digital input provides remote dry contact closure to reset the limit state. Alarm relays can be configured for high or low alarm setpoints, latching or non-latching operation, alarm blocking, PV rate of change alarm, loop break alarm and diagnostic alarm functions.
Communication and Configuration
Communication options include RS485 Modbus RTU and Ethernet 10/100M Base-T TCP/IP for connection with a host computer or PLC. Bluetooth communication supports non-intrusive configuration while maintaining front-face protection integrity.
The Easyset mobile device app can create configurations, edit live controller settings, prepare offline configurations and download them to the controller later. It also supports configuration upload, maintenance information review and firmware upgrade functions.
Operator Interface
The UDC2800 uses a TFT LCD display for process variable, setpoint, diagnostic messages and operating information. English prompts guide the operator through configuration, helping make setup and daily operation easier.
The controller provides indicators for alarm status, control mode, temperature units, digital input status, relay status, Bluetooth status, Modbus status and Ethernet communication status depending on configuration.
Technical Highlights
Universal switching power operates from 90 to 264 Vac, 50/60 Hz without jumpers. 24 Vac/dc instrument power is available as an option.
Analog input features include configurable upscale, downscale, failsafe or none burnout selections, thermocouple health monitoring, software input filtering from off to 120 seconds and high noise immunity for industrial environments.
The controller is housed in a 4.5 inch deep black plastic case with dark gray elastomer bezel and is panel mounted in a 1/4 DIN cutout. Wiring connections are made through screw terminals on the rear case.
Typical Applications
Honeywell UDC2800 can be used in temperature control, process limit control, furnace and oven control, industrial heating systems, manufacturing process monitoring, equipment protection and automation panels that require alarm and communication functions.
It is suitable for plants needing a compact digital limit controller with universal input, reliable alarms, flexible outputs, Bluetooth configuration and optional network communication.
