Selectable sampling time among 50ms, 100ms, and 250ms.

Selectable sampling time makes the FB Series suitable for any application ranging from pressure control requiring fast response to precise control requiring highest resolution. The selections are 100ms (factory setting) usually suitable for most of standard applications, 50ms for fast response applications, and 250ms for precise control requiring high-resolution. The PID parameters can be set in 1/10 unit which supports fast and accurate control. Ramp-to-setpoint and output-change-limiter functions are each settable for UP and DOWN so that a special heater can be controlled precisely.

Selectable PID control algorithm

PID control algorithm is selectable in the FB Series to achieve the most precise control for various applications.
PV Derivative PID : suitable for fixed setpoint control (Factory setting)
Deviation Derivative PID : suitable for ramp control using ramp-to-setpoint function and cascade control.

Advanced Heat/Cool PID algorithm with Undershoot Suppression

Advanced Heat/Cool PID algorithm achieves stable control by the Undershoot Suppression (USS) function, and independent P-I-D settings for both Heat and Cool which are effective for applications with strong cooling gain. Control Response t*e selection is settable to avoid overshoot at start-up and against external disturbance. The FB Series also offers selection of water cool and air cool PID control algorithm.
