BFC-16 Controller

The BFC-64 Channel Controller provides simultaneous display and alarm functions for up to 64 transmitters or sensors. 16, 32, 48 and 64-channel display modes–with I/O modules–arranged in groups of 16 channels allow economical configuration and expansion of systems. Easy to configure
and user-friendly, the BFC-64 is ideal for centralizing display and alarm functions in critical multi-point monitoring applications.

  • Accepts inputs from up to sixteen inputs from many sensor types and signal ranges. Modbus® master capability allows input data to be retrieved via RS-485.
  • Eight channel display mode and option boards allow economical configuration of systems requiring 8 channels or less and is easily expandable for future system growth.
  • Dual Modbus® RS-485 serial ports for simultaneous master / slave operation.
  • Three independent alarm levels per channel. “Relay Acknowledge” feature allows silencing of external audible devices during alarm conditions.
  • Graphic LCD readout displays monitored data as bar graphs, engineering units and 30 minute trends. Alarm LED’s flash with new alarms and become steady after acknowledgement.
  • Modbus® master / slave RS-485 serial port interfaces to Modbus® devices such as other Buckeye Detection Systems controllers, PLC’s, DCS and PC’s.
  • Cal Mode offers push button zero / span calibration functionality for direct sensor input applications.
  • Authorization mode allows locking of critical configuration settings.
  • Touch and magnetic keypad are standard for non-intrusive operation in potentially hazardous locations.
  • Enclosures include: Non-metallic, Epoxy Coated Steel, 316 S.S., NEMA 4X, and NEMA 7 explosion proof wall mount options.
  • Certified to CSA C22.2.No. 152 for combustible detection and Class I, Division 2, Groups A, B, C and D.
  • Non-volatile memory retains all configuration data indefinitely.
  • RS-485 Modbus® master / slave port for up to 128 devices to be multi-dropped on a single data high way for interrogation by another Modbus® master.
  • Six additional 5 amp SPDT discrete channel alarm relays available. (Two are standard)
