NI FP-DIO-550

16-Channel Digital Input/Output Module for NI FieldPoint

  • For new designs, NI recommends using CompactRIO.
  • 8 sourcing outputs, 10 to 30 VDC, 250 mA per channel
  • 8 sinking/sourcing inputs, 11 to 30 VDC
  • 7 mA current-limited input protection
  • -40 to 70 °C operating range
  • Output short-circuit protection

Important note: For new designs, National Instruments recommends CompactRIO hardware (see Resources tab).

The NI FP-DIO-550 is a 16-channel digital input/digital output module. It can measure eight digital inputs with a range of 11 to 30 VDC and source eight outputs from 10 to 30 VDC with 250 mA per channel. This module offers both digital input and digital output channels, effectively replacing two modules with one (DI + DO). It provides 250 V, CAT II, safety isolation to backplane and offers discrete sensor and actuator interfacing. This module also delivers a range of 1 µs to 65 ms and incorporates a user-selectable input filter to reject noise. In addition, you can configure the module so that digital outputs turn on only when the states of digital input channels match specific patterns.
