The Fuzzy Logic plus PID microprocessor-based profiling controller with many segments of the ramp and dwell, incorporate two bright, easy to read 4-digit LED displays, indicating process value and setpoint value. The Fuzzy Logic 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.
As a professional and experienced manufacturer, we supply high-performance and quality ramp soak controllers, which are also called programmable temperature controllers.
Feature
- Total 9 profiles, a profile with 16, 32 or 64 segments at most
- Each segment to be configured as a ramp or dwell(soak)
- Fast A-D sampling rate (5 times/s)
- After an event, the process goes to run, hold, abort, manual, failure transfer, off mode, next segment or select the second PID values
- High accuracy of 18-bit A to D input, and 15-bit D to A output
- The fast sample rate of 200 msec
- Fuzzy control to reach set point at the least overshooting and less time
- Up to three relays are configurable for event output
- Analog retransmission of process value & setpoint value
- Optional RS-485 or 232 communications
- Programmable port for easy configuration or calibration
- Lockout protection for security requirement
- Bumpless transfer of safely control while sensor breaks
- Digital filter to improve the stability of process value
- SEL function for easy operation
