Brainchild BTC Series Established Process and Temperature Controllers



The Fuzzy Logic plus PID microprocessor-based temperature controller, incorporate one bright, easy to read 4-digit LED display, 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.

Feature

  • Easy-to-use
  • Fuzzy modified PID heat & cool control
  • Fast A-D sampling rate (5 times/s)
  • Universal input (PT100, thermocouple)with high accuracy 18-bit A-D
  • Analog output (linear current or voltage)uses high accuracy 15-bit D-A
  • RS-485 RS-232 interface
  • Programming port provided on board
  • Support manual control & auto-tune function
  • Wide variety of alarm mode selection
  • Lockout protection control
  • Bumpless transfer during failure mode
  • Soft-start ramp and dwell timer
  • Bright display stabilized with digital filter
  • Front panel sealed to NEMA 4X & IP65(model C21)
  • UL/CSA/CE approval
  • High performance with low cost
