The Honeywell UDC1200 Series MICRO-PRO Universal Digital Controllers are compact, microprocessor-based devices designed to monitor and control process variables such as temperature, pressure, and level. Their 1/16 DIN size (48mm x 48mm) makes them ideal for applications with limited panel space. These controllers are widely used across various industries, including environmental chambers, furnaces, ovens, packaging machines, and processes within the plastics and food and beverage sectors.

The UDC1200 series supports a variety of inputs, including thermocouples, RTDs, and linear mA or voltage signals, providing flexibility for diverse applications. The dual LED display simultaneously shows process variables (PV) and setpoints (SP), enabling enhanced operational clarity. Advanced control algorithms, including PID, On/Off, and Three Position Step Control (TPSC), provide precise process regulation. Configurable alarms alert operators to process deviations, while the controllers offer a range of output types—relay, SSR driver, and linear outputs such as 4-20mA or 0-10V—catering to specific application needs. Optional RS485 communication allows integration into supervisory systems, and the tactile keypad ensures straightforward configuration and operation. The robust build meets IP66 standards, offering protection against dust and water.
Part Number Naming Convention
The UDC1200 Series follows a structured part number format that specifies the controller’s configuration. A typical part number is formatted as follows:
DC120″X”-“I”-“II”-“III”-“IV”-“V”-“VI”-“VII”
