Technical Data

Description

780179-01 | NI 9403 digital TTL I / O module with 32 channels (conformal coating)

The channels of the NI ‑ 9403 digital I / O module can be configured as inputs or outputs for each channel during operation. Each channel has transient isolation between the I / O channels and the backplane. Reconfigurable I / O technology (CompactRIO only) allows the LabVIEW FPGA to be used to program the NI ‑ 9403 module and implement custom high-speed counters / timers, digital communication protocols, pulse generation, and other applications. The NI ‑ 9403 can only be used as a static (software controlled) digital I / O module in a CompactDAQ chassis. The modules cannot be used to route timing or trigger signals.

Product features:

  • Number of pure digital input channels: 0
  • Number of pure digital output channels: 0
  • Number of bidirectional digital channels: 32
  • Logic level of the digital I / O: 5V TTL
  • Maximum update rate: 7 µs
  • Current flow direction: Current sinking input Current sinking output Current supplying output Current supplying input
  • Isolation of the digital I / O: 60 VDC isolation of the channel from ground
  • Connection type front: D-Sub
  • Protective coating: yes
  • With housing: yes
  • Supported hardware platform: CompactDAQ, CompactRIO
