Process Temperature Controllers — Frequently Asked Questions

Common questions about Honeywell UDC controllers and Yokogawa UT35A process controllers. Contact our team or call (901) 458-2000 for configuration help.

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. Available with single or dual relay outputs and 90–264 VAC power supply.

What is the difference between the Honeywell UDC1200 and UDC2800?

The UDC1200 is a compact 1/16 DIN (48mm × 48mm) panel-mount controller with basic digital control and relay outputs — available as a standard controller or FM/UL-approved limit controller. The UDC2800 is a larger 1/4 DIN (96mm × 96mm) controller with significantly more capability: Accutune III auto-tuning with fuzzy logic, Bluetooth smartphone configuration, TFT color display with trend graphics, universal input, and NEMA 4X/IP66 housing. Choose UDC1200 for basic control in a compact footprint; choose UDC2800 when you need advanced auto-tuning, Bluetooth configuration, or a more rugged enclosure.

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

An FM-approved limit controller monitors a process temperature and initiates a safety shutdown if it exceeds a programmed limit — acting as a final safety layer independent of the main control loop. FM (Factory Mutual) approval means the device has been independently certified for safety applications. FM-approved limit controllers are required by NFPA and ASME codes on commercial boilers and industrial heating equipment as protection against overheat conditions. The Honeywell DC120L (UDC1200 Limit) and DC2800-E/EE (UDC2800 Limit) series are FM-approved for these applications.

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 — accepting thermocouple, RTD, and DC current/voltage process signals — PID control with auto-tuning, and a compact panel-mount footprint. Used for temperature control of industrial ovens, furnaces, dryers, and process equipment. The UT35A-L00-11-00 is the primary stocked model — contact us for other UT35A configurations.
