Q: What is the Honeywell UDC1200 used for?

The Honeywell UDC1200 (DC120x series) is a compact 1/16 DIN digital controller and FM-approved limit controller for industrial process temperature control. It is used on boilers, ovens, furnaces, kilns, and industrial process equipment requiring a panel-mount temperature controller or safety temperature limit. The DC120L limit controller variant is FM and UL approved for safety shutoff applications — it monitors process temperature and shuts down the process if temperature exceeds the programmed limit. Available with single or dual relay outputs and 90–264 VAC power supply.

Q: What is the difference between the Honeywell UDC1200 and UDC2800?

The UDC1200 (DC120x series) is a 1/16 DIN controller — a compact panel-mount size measuring 48mm x 48mm. It provides basic digital control with relay outputs and is available in standard controller and FM-approved limit controller versions. The UDC2800 (DC2800 series) is a larger 1/4 DIN controller (96mm x 96mm) with significantly more capability — Accutune III auto-tuning with fuzzy logic for self-optimizing PID control, Bluetooth configuration via smartphone app, TFT color display with trend graphics, universal input accepting thermocouple, RTD, and process signal, and NEMA 4X/IP66 housing for wash-down environments. Choose UDC1200 for basic temperature control in a compact footprint; choose UDC2800 when you need advanced control features, auto-tuning, or a more rugged enclosure.

Q: What is an FM-approved limit controller and when is it required?

An FM-approved limit controller is a safety device that monitors a process variable (typically temperature) and initiates a safety shutdown if the variable exceeds a programmed safety limit. Unlike a regular process controller that continuously regulates the process, a limit controller acts as a final safety layer independent of the main control loop. FM approval (Factory Mutual) means the device has been independently tested and certified for use in safety applications. FM-approved limit controllers are required by NFPA and ASME codes on commercial boilers and industrial heating equipment where a primary control failure could result in an unsafe overheat condition. The Honeywell DC120L (UDC1200 Limit) and DC2800-E/EE (UDC2800 Limit) series are FM-approved.

Q: What is the Yokogawa UT35A?

The Yokogawa UT35A is a compact 1/16 DIN process controller for industrial temperature and process variable control. It features universal input capability — accepting thermocouple, RTD, and DC current/voltage process signals — PID control with auto-tuning, and a compact panel-mount footprint. The UT35A is used in industrial process control applications including temperature control of ovens, furnaces, dryers, and process equipment. The UT35A-L00-11-00 is the primary model stocked by Memphis Control Center.
