NI-9213

GETTING STARTED GUIDE

NI 9213

16 TC, ±78 mV, 24 Bit, 75 S/s Aggregate

This document explains how to connect to the NI 9213.

Note Before you begin, complete the software and

hardware installation procedures in your chassis

documentation.

Note The guidelines in this document are specific to

the NI 9213. 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.

Caution Electrostatic Discharge (ESD) can damage

the NI 9213. To prevent damage, use industry-standard

ESD prevention measures during installation,

maintenance, and operation.

Safety Guidelines

Operate the NI 9213 only as described in this document.

Caution Do not operate the NI 9213 in a manner not

specified in this document. Product misuse can result in

a hazard. You can compromise the safety protection

built into the product if the product is damaged in any

way. If the product is damaged, return it to NI for

repair.

Hazardous Voltage This icon denotes a warning

advising you to take precautions to avoid electrical

shock.

Safety Voltages

Connect only voltages that are within the following limits:

Channel-to-channel None

Channel-to-earth ground

Continuous 250 Vrms,

Measurement Category II

Withstand up to

4,000 m

3,000 Vrms, verified by a 5 s

dielectric withstand test

Measurement Category II is for measurements performed on

circuits directly connected to the electrical distribution system.

This category refers to local-level electrical distribution, such as

NI 9213 Getting Started Guide | © National Instruments | 3

that provided by a standard wall outlet, for example, 115 V for

U.S. or 230 V for Europe.

Caution Do not connect the NI 9213 to signals or use

for measurements within Measurement Categories III

or IV.

Safety Guidelines for Hazardous Voltages

If hazardous voltages are connected to the device, take the

following precautions. A hazardous voltage is a voltage greater

than 42.4 Vpk voltage or 60 VDC to earth ground.

Caution Ensure that hazardous voltage wiring is

performed only by qualified personnel adhering to local

electrical standards.

Caution Do not mix hazardous voltage circuits and

human-accessible circuits on the same module.

Caution Ensure that devices and circuits connected to

the module are properly insulated from human contact.

Caution When module terminals are hazardous

voltage LIVE (>42.4 Vpk/60 VDC), you must ensure

that devices and circuits connected to the module are

4| ni.com | NI 9213 Getting Started Guide

properly insulated from human contact. You must use

the NI 9940 connector backshell kit to ensure that the

terminals are not accessible.

Safety Guidelines for Hazardous Locations

The NI 9213 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

and Ex nA IIC T4 hazardous locations; and nonhazardous

locations only. Follow these guidelines if you are installing the

NI 9213 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 off or the

area is known to be nonhazardous.

Caution Do not remove modules unless power has

been switched off or the area is known to be

nonhazardous.

Caution Substitution of components may impair

suitability for Class I, Division 2.

Caution For Division 2 and Zone 2 applications,

install the system in an enclosure rated to at least IP54

as defined by IEC/EN 60079-15.

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 9213 has been evaluated as Ex nA IIC T4 Gc equipment

under DEMKO Pizza ATEX Pizza and is IECEx UL 14.0089X

certified. Each NI 9213 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 9213 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 You must make sure that transient

disturbances do not exceed 140% of the rated voltage.

6| ni.com | NI 9213 Getting Started Guide

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.

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

NI 9213 Getting Started Guide | © National Instruments | 7

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.

Caution To ensure the specified EMC performance,
