NI PCI-6518 (16 Inputs, 16 Source Outputs)

Low-Cost 37-Pin Industrial Digital I/O -- 30 V, Bank-Isolated

Configure Page for: Print PDF Rich Text
  • 16 bank-isolated sink/source inputs (±30 VDC)
  • 16 bank-isolated source outputs (±30 VDC, 350 mA for one channel, 75 mA for all channels)
  • Low-cost solution with advanced features for industrial control and manufacturing test applications
  • Watchdogs, programmable power-up states, change detection, input filters, high current drive
  • High-reliability industrial feature set: guaranteed industrial 24 V logic thresholds
  • NI-DAQmx measurement services software for highest productivity and performance


The National Instruments PCI-6518 board offers 16 optically isolated sink/source input channels, and 16 optically isolated source output channels with low-cost 37-pin accessory connectivity. The NI PCI-6518 inputs and outputs are optically isolated in banks of 16 channels. With programmable power-up states, you can configure the initial output states in software, to ensure safe operation when connected to industrial actuators (pumps/valves/motors/relays). Using digital I/O watchdogs, the board can go to a configurable safe output state if a computer or application fault occurs. NI-DAQmx makes it fast and easy to configure your board and take advantage of all the high-reliability industrial features with automatic code generation in LabVIEW, ANSI C, Microsoft Visual C++, or Microsoft .NET Languages (C# and Visual Basic .NET). For optical isolation in banks of eight channels, consider the PCI-6514 board. For channel-channel isolation and a ±60 V output range, consider the PCI-6528 board.
