System compatibility

NI-9381 belongs to NI C series DAQ platform.It is designed exclusively for CompactRIO chassis,supported by LabVIEW FPGA,widely used for general-purpose signal acquisition,voltage output and digital logic control in small automated test and control systems.It is spare part for legacy test equipment overhaul.

Function

NI-9381 is integrated multi-function I/O C-series module combining analog input,analog output and digital I/O in one unit.Multiplexed analog circuit shares timing engine for cost-effective signal measurement and generation.It is suitable for closed-loop control,simulation signal output and simple digital interlock on CompactRIO platform.

Installation

Insert NI-9381 into CompactRIO chassis slot,tighten front panel screw.Connect analog and digital signal wiring to 37pin D-SUB connector.Use LabVIEW FPGA for programming.Take ESD protection before installation.

Interface

‑37pin D-SUB multi I/O connector

‑C series backplane edge connector

‑Module status LED indicators

Feature

NI-9381 classic NI CompactRIO multifunction I/O module.Typical faults:D-SUB pin oxidation,ADC/DAC drift,LVTTL digital channel damage.Inspect wiring and channel reading before replacement.

Diagnostic

Fault phenomenon:no analog reading,unstable AO output,DIO no response.Check D-SUB cable,CompactRIO backplane connection,FPGA program and module hardware status.

Product Brief

NI-9381 is NI C series integrated multifunction I/O module with 12-bit 8AI,8AO and 4 LVTTL DIO,0~5V signal range,20kS/s aggregate rate,only compatible with CompactRIO for general industrial control and signal test.Mainly used for maintenance and replacement of old test equipment.ESD protection must be followed during handling.
