The MULTISPAN UTC-221P is a temperature controller designed for industrial applications, offering precise temperature management with a range of configurable features.

Function Description:

The UTC-221P serves as a temperature controller, capable of monitoring and regulating temperature based on user-defined set points. It supports various control methods, including PID control with auto-tuning, Time Proportional (TP) control, and ON-OFF control, making it versatile for both heating and cooling applications. The device displays both the Process Value (PV) and the Set Value (SV) on a dual-color 7-segment display, providing clear visual feedback. An auto-tuning function simplifies setup by automatically calculating and setting optimal PID parameters (Proportional Band, Integral Time, Derivative Time, and Cycle Time) based on process characteristics. A tuning LED indicates when auto-tuning is active, and the process restarts automatically if power is interrupted before completion.
