Differences Between the BNC-2090 and BNC-2090A Connector Blocks Hardware: Multifunction DAQ (MIO)>>Connector Blocks>>BNC-2090A, Multifunction DAQ (MIO)>>Connector Blocks>>BNC-2090
Problem: What are the differences between the BNC-2090 and the BNC-2090A DAQ accessory modules? Which one is recommended and in what cases? Solution: The BNC-2090A and the BNC-2090 are shielded, 1U, 19” rack-mountable adapters with 22 signal-labeled BNC connectors to simplify connections to your I/O signals. The accessory provides access to all analog I/O, analog and digital triggers, clocks for synchronization purposes, and two user-defined signals through BNC connectors. Digital I/O signal connectivity is provided through 29 spring terminals. The BNC-2090A includes easy access to areas where users can build custom signal conditioning circuitry including low-pass filters, high-pass filters, and voltage dividers (attenuators). 68-pin SCSI connectors are featured on the front and back of the accessory, providing additional options for connecting to the data acquisition device. The BNC-2090A can connect to any 68-pin M Series (connectors 0 and 1), E Series, S Series or B Series DAQ devices. The BNC-209A is a RoHS-compliant accessory. For existing users of the BNC-2090, the BNC-2090A provides complete backward compatibility with existing systems. The BNC-2090A provides easier assembly/disassembly, easier access to areas for custom signal conditioning, a smaller footprint, RoHS compliance, and optimization for M Series and other NI-DAQmx supported devices. NI recommends the BNC-2090A instead of the BNC-2090 for all use cases. Related Links: BNC-2090A Resource Page BNC-2090 Resource Page Attachments:
