Specifications
This section lists the specifications of the NI FlexRIO adapter module (NI 5761). Pair these
specifications with the specifications listed in the NI FlexRIO FPGA Module Installation Guide and
Specifications. For more information about safety and electromagnetic compatibility refer to the Read
Me First: Safety and Electromagnetic Compatibility document included in your hardware kit or
available at
ni.com/manuals.
Caution To avoid permanent damage to the NI 5761, disconnect all signals connected to the NI 5761
before powering down the module, and only connect signals after the module has been powered on
by the NI FlexRIO FPGA module.
Note All numeric specifications are typical unless otherwise noted. All graphs illustrate the
performance of a representative module.
Typical values describe useful product performance that are not covered by warranty. Typical values
cover the expected performance of units over ambient temperature ranges of 23 ±5 °C with a 90%
confidence level, based on measurements taken during development or production.
