Overview

Product overview

Key product information and technical features.

The PXI-6515 is an industrial digital I/O interface for PXI systems. Its 64 channels are divided into 32 input-only and 32 output-only channels, with eight banks of isolated channels and single-ended signaling.

Each input bank can be wired in a source or sink configuration. Software-selectable input filters support glitch reduction and switch or relay debouncing, while programmable power-up states and digital I/O watchdogs provide configurable output behavior during startup and fault conditions.

  • 32 sink/source digital inputs and 32 sinking digital outputs.
  • Bank-isolated architecture with eight banks of channels.
  • 24 V digital I/O logic levels with single-ended signaling.
  • Programmable input filters for glitches, spikes, and switch or relay debouncing.
  • Software-configurable power-up output states.
  • Digital I/O watchdogs can switch outputs to a configurable safe state following a computer or application fault.
  • PXI Hybrid bus connection and SCSI-type front connection.
