The XMTD-2201 is a robust, reliable workhorse when properly configured. Its strength lies in the Auto-Tune feature, which eliminates guesswork for PID constants. Always keep a printed copy of your specific unit’s parameter table (supplied by your vendor) as firmware variations exist. For wiring diagrams, look for the silk-screen directly on the controller’s metal casing.
The XMTD-2201 is a member of the ubiquitous PID (Proportional-Integral-Derivative) temperature controller family, commonly found in industrial ovens, injection molding machines, packaging sealers, and laboratory equipment. Known for its 1/16 DIN size and dual-display LED interface, this unit bridges the gap between simple on/off thermostats and complex PLC-based systems. xmtd-2201 manual
