Overview

Product overview

Key product information and technical features.

The PCI-6519 is a computer-based industrial digital I/O device for a PCI host system. It provides 16 digital input-only channels and 16 digital output-only channels through a D-SUB front connection, with single-ended signaling and no bidirectional channels.

The inputs support sinking or sourcing configurations, while the outputs are sinking. Programmable power-up states and digital I/O watchdogs allow outputs to be assigned a configurable safe state following a computer or application fault.

  • 32 dedicated digital I/O channels: 16 sink/source inputs and 16 sinking outputs.
  • Bank-isolated digital I/O with 30 VDC isolation and 24 V logic levels.
  • Each input bank can be wired in a sourcing or sinking configuration.
  • Programmable power-up states support defined output behavior at startup.
  • Digital I/O watchdogs can switch outputs to a configurable safe state after a computer or application fault.
  • Operating temperature range of 0 °C to 55 °C.
