TTC BLS-148 48-Channel Bi-Level Multiplexer Card Data Sheet

The BLS-148 is a plug-in bi-level multiplexer card for use in Curtiss-Wright’s EDAU-20XX and CDAU-20XX data acquisition system products. The card is intended for applications that require detection of logic levels, switch status or other “on/off” signal types. Threshold levels are user-programmable to accommodate a wide range of inputs. Bi‑level data is encoded as  four (4) 12-bit data words or one (1) 47-bit word (user-programmable) for transmission in the system PCM output format. The card has 3 data trigger/latch modes and the capability for timestamping discrete data inputs. These features result in a high-performance discrete card for interfacing with a wide variety of digital subsystems.
