FDC-8300 Fuzzy Logic plus PID microprocessor-based controller, incorporates a bright,
easy to read 4-digit LED display, indicating process value. The technology
enables a process to reach a predetermined set point in the shortest time, with the
minimum of overshoot during power-up or external load disturbance. The units are
housed in a 1/4 DIN case, measuring 96 mm x 96 mm with 53 mm behind panel depth.
The units feature three touch keys to select the various control and input parameters.
Using a unique function, you can put at most 5 parameters in front of user menu by using
contained in the setup menu. This is particularly useful to OEM's as it is easy
to configure menu to suit the specific application.

is observed. Unlike auto-tune, Self-tune will produce less disturbance to the process
during tuning, and can be used any time.
