The BLS-148 is a plug-in bi-level multiplexer card for use in Curtiss-Wright's EDAU-20XX and CDAU-20XX 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.
Key Features
- 48 channels per card
- Programmable input threshold +10V to -10V on a word basis
- Programmable floating input detect “0”/“1” on a word basis
- Programmable input trigger modes
- Sample-based on PCM format
- Sample-based on bit trigger
- Group sample based on bit trigger
- External trigger
Applications
- Computers I/F via parallel digital I/O
- Monitor BCD-compatible equipment
- I/F with parallel time code
- Switch/relay status monitoring
The CDAU-20XX is a CAIS-compatible data acquisition unit (DAU) for interfacing with a variety of analog/digital sensors and sources.
BLS-148 48-Channel Bi-Level Multiplexer Card
The BLS-148 is a plug-in bi-level multiplexer card for use in Curtiss-Wright's EDAU-20XX and CDAU-20XX 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.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
