FDC-9300 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 1/16 DIN case, measuring 48 mm x 48 mm with 75 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.

FDC-9300 is powered by 11-28 or 90 - 264 VDC / AC supply, incorporating a 2 amp.
control relay as standard. Up to two additional optional relay outputs can be
supported. Output two can be a cooling relay or alarm or dwell timer.The third relay
performs as a programmable alarm. Alternative output options include SSR Drive,
Triac, 0/4 - 20 mA and 0 - 10 volts.
FDC-9300 is fully programmable for PT100,
thermocouple types J, K, T, E, B, R, S, C, P, 0 - 20mA, 4 -20mA and voltage signal input,
with no need to modify the unit. The input signals are digitized by using a
converter. Its
allows the FDC-9300 to control fast processes such as
pressure and flow.
is incorporated. The self- tune can be used to optimize the
control parameters as soon as undesired control result is observed. Unlike auto-tune,
Self-tune will produce less disturbance to the process during tuning, and can be used
any time.
