BFC-64 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.
