The FB400/900 feature Brilliant
PID with autotuning and a choice of control
algorithm for fixed setpoint, ramping setpoint and
cascade control applications.
The FB400 and FB900 feature a
measurement accuracy of better than ±0.1% of
Selectable input sampling times of
50, 100 and 250mseconds enable the FB range to be used
for a wide range of applications from fast pressure or
flow control to precision temperature control.
Selectable Control Type
The control type may be configured
by the user for heat, cool, heat/cool and valve motor
In addition to the standard
‘single shot’ autotuning a fast start up
autotuning function is included which may be used at
process start up or continuously depending on the
A wide range of thermocouple,
resistance thermometer, current and voltage inputs are
Relay, SSR, current, voltage and
open collector outputs are available.
Loading Port for Simple
Configuration and Data Logging
The FB400/900 control and
parameter settings may be downloaded using a PC. During
this operation it is not necessary to power the
instrument as power is supplied by the USB port.
Instrument Monitoring and Data Logging
The loader port may also be used
for data logging using the free software supplied. Data
can be exported in .csv format. Graphic display and
trend functions are also included.
In addition to the standard loader
port, ANSI and Modbus communications are also available
for RS232, 485 and 422. A second RS485 communication
port may be used for inter-controller communication for
the following applications: temperature profile
self-learning where temperature rate of rise will be
automatically controlled to avoid uneven heating rates,
temperature ratio setting for master/slave remote
setpoint applications and cascade control.
Memory Area Location of Set and
The FB range can store up to eight
groups of setpoint, alarm values and PID control terms.
Selection of each group may be accessed from the front
panel or remotely using digital input contacts or
By linking memory areas and using
the setpoint ramping and soak time parameters it is
possible to use the FB400/900 as a programmer
Power Feed Forward (PFF)
This option constantly monitors
the electrical load through a dedicated transformer.
The instruments control output is then automatically
adjusted to compensate for fluctuations in the power
