Filtered Analog Input Expansion: MSXB 048
When you must eliminate aliases
The Microstar Laboratories Filtered Analog Input Expansion Board, part number MSXB 048, provides filtered analog input expansion for Analog Backplane systems. The Filtered Analog Input Expansion Board is compatible with the MSXB 030-01 and MSXB 031-01 Analog Backplanes.
The MSXB 048 Filtered Analog Input Expansion Board has a four-pole low-pass Butterworth filter on each of its 16 single-ended channels. For DAP applications that require analog filters to take out all above-Nyquist frequencies before signal conversion, it simply replaces the MSXB 037 Analog Input Expansion board. Signal inputs normally connect to the MSXB 048 through a panel-mount DB-37 connector.
The Microstar Laboratories Channel Architecture allows sixteen MSXB 048 boards to connect to a single DAP board for up to 256 channels of filtered input. The MSXB 048 typically draws 8 Watts of +5V power. The channel architecture includes three ways to supply power to the 68-line analog backplane in the MSIE industrial enclosure: from the PC, from an external source, or from a factory-installed power supply built into the industrial enclosure.
Low channel-count applications that draw power from the PC, and that do not require the expansion potential offered by the Microstar Laboratories Channel Architecture, may instead use an MSXB 048 board packaged in a Single-Board Enclosure (SBE). Low channel-count applications that do not require the EMI shielding offered by the Microstar Laboratories Channel Architecture hardware -- but that do require anti-aliasing measures -- can use stand-alone versions of the MSXB 048. Signal inputs for these versions connect to a board-mount shrouded header.
As well as sampling input signals, the MSXB 048 can sample an onboard +5V reference and the onboard signal ground. This allows software offset calibration and verification of proper operation without changing the input cabling.
