Overview

This document explains how to connect to the NI-9403.

Note Before you begin, read the NI-9403 Safety, Environmental, and

Regulatory Information document on ni.com/manuals and complete the

soware and hardware installation procedures in your chassis

documentation.

Note The guidelines in this document are specific to the NI-9403. The

other components in the system might not meet the same safety ratings.

Refer to the documentation for each component in the system to

determine the safety and EMC ratings for the entire system.

Safety Guidelines

Caution Observe all instructions and cautions in the user documentation.

Using the product in a manner not specified can damage the product and

compromise the built-in safety protection.

toute autre façon que celle spécifiée risque de l'endommager et de

compromettre la protection de sécurité intégrée.

Safety Voltages

Connect only voltages that are within the following limits:

Channel-to-COM ±30 V maximum on up to 8 channels at a time, Measurement Category I

Isolation

NI-9403 Getting Started

Channel-to-channel None

Channel-to-earth ground

Continuous 60 V DC, Measurement Category I

Withstand

Up to 3,000 m altitude 1,000 V RMS, verified by a 5 s dielectric withstand test

Up to 5,000 m altitude 860 V RMS, verified by a 5 s dielectric withstand test

Safety Guidelines for Hazardous Locations

The NI-9403 is suitable for use in Class I, Division 2, Groups A, B, C, D, T4 hazardous

locations; Class I, Zone 2, AEx nA IIC T4 Gc and Ex nA IIC T4 Gc hazardous locations;

and nonhazardous locations only. Follow these guidelines if you are installing the

NI-9403 in a potentially explosive environment. Not following these guidelines may

result in serious injury or death.

Caution Do not disconnect I/O-side wires or connectors unless power has

been switched o or the area is known to be nonhazardous.

Caution Do not remove modules unless power has been switched o or

the area is known to be nonhazardous.

Caution Substitution of components may impair suitability for Class I,

Division 2, or Zone 2.

Caution The system must be installed in an enclosure certified for the

intended hazardous (classified) location, having a tool secured cover/door,

where a minimum protection of at least IP54 is provided.

Caution For Division 2 and Zone 2 applications, connected signals must

be within the following limits.

Capacitance 0.2 µF maximum

Special Conditions for Hazardous Locations Use in Europe and

Internationally

The NI-9403 has been evaluated as Ex nA IIC T4 Gc equipment under

DEMKO 07ATEX 0626664X and is IECEx UL 14.0089X certified. Each NI-9403 is marked

II 3G and is suitable for use in Zone 2 hazardous locations, in ambient

temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI-9403 in Gas Group IIC

hazardous locations, you must use the device in an NI chassis that has been

evaluated as Ex nC IIC T4, Ex IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Caution Transient protection shall be provided that is set at a level not

exceeding 140% of the peak rated voltage value of 85 V at the supply

terminals to the equipment.

Caution The system shall only be used in an area of not more than

Pollution Degree 2, as defined in IEC/EN 60664-1.

Caution The system shall be mounted in an ATEX/IECEx-certified

enclosure with a minimum ingress protection rating of at least IP54 as

defined in IEC/EN 60079-15.

Caution The enclosure must have a door or cover accessible only by the

use of a tool.

Electromagnetic Compatibility Guidelines

This product was tested and complies with the regulatory requirements and limits

for electromagnetic compatibility (EMC) stated in the product specifications. These

requirements and limits provide reasonable protection against harmful interference

when the product is operated in the intended operational electromagnetic

environment.

NI-9403 Getting Started

This product is intended for use in industrial locations. However, harmful

interference may occur in some installations, when the product is connected to a

peripheral device or test object, or if the product is used in residential or

commercial areas. To minimize interference with radio and television reception and

prevent unacceptable performance degradation, install and use this product in strict

accordance with the instructions in the product documentation.

Furthermore, any changes or modifications to the product not expressly approved

by National Instruments could void your authority to operate it under your local

regulatory rules.

Special Conditions for Marine Applications

Some products are approved for marine (shipboard) applications. To verify marine

approval certification for a product, visit ni.com/product-certifications, search by

model number, and click the appropriate link.

Notice In order to meet the EMC requirements for marine applications,

install the product in a shielded enclosure with shielded and/or filtered

power and input/output ports. In addition, take precautions when

designing, selecting, and installing measurement probes and cables to

ensure that the desired EMC performance is attained.

Preparing the Environment

Ensure that the environment in which you are using the NI-9403 meets the following

specifications.

Operating temperature (IEC 60068-2-1, IEC 60068-2-2) -40 °C to 70 °C

Operating humidity (IEC 60068-2-30) 10% RH to 90% RH, noncondensing

Pollution Degree 2

Maximum altitude 5,000 m

Indoor use only.

Signal Name Description

DIO Each channel includes a DIO pin to which you can connect a digital input or output

device.

COM DIO channels are internally referenced to COM, so you can use any of the four COM

lines as a reference for the external signal.

RSVD This channel is reserved and is not a user-facing signal.

Overcurrent/Short-Circuit Protection

The overcurrent protection allows only a specified amount of current through the

output channels to protect the NI-9403 from short circuits. If the NI-9403 goes into

an overcurrent state, the module sets all the DIO channels to high impedance for

approximately 280 ms.

When the channels are in an overcurrent state, the NI-9403 can accept new line

direction configuration and output state data but cannot pass valid input data to the

soware.

Aer the overcurrent protection period, the NI-9403 automatically recovers to the

latest direction configuration and output state. If the overcurrent condition still

exists, the module again sets the channels to high impedance. This cycle continues

until the overcurrent condition is removed.
