National Instruments NI 9216 Getting Started Manual

GETTING STARTED GUIDE

NI 9216

8 RTD, 0 Ω to 400 Ω, 24 Bit, 400 S/s Aggregate,
PT100

This document explains how to connect to the NI 9216. In this
document, the NI 9216 with spring terminal and the
NI 9216 with DSUB are referred to inclusively as the NI 9216.

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 9216. 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 9216 with spring terminal. To prevent damage,
use industry-standard ESD prevention measures during
installation, maintenance, and operation.

Safety Guidelines

Operate the NI 9216 only as described in this document.

Caution Do not operate the NI 9216 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 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.

You can connect hazardous voltages only to the
NI 9216 with spring terminal. Do not connect hazardous voltages
to the NI 9216 with DSUB.

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
properly insulated from human contact.

Safety Voltages

Connect only voltages that are within the following limits:

NI 9216 with Spring Terminal Isolation Voltages

Channel-to-channel None

Channel-to-earth ground

Continuous 250 Vrms,

Measurement Category II

Withstand up to
5,000 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
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 9216 with spring

terminal to signals or use for measurements within
Measurement Categories III or IV.

NI 9216 with DSUB Isolation Voltages

Channel-to-channel None

Channel-to-earth ground

Continuous 60 VDC,

Measurement Category I

Withstand

Up to 3,000 m 1,000 Vrms, verified by a 5 s

dielectric withstand test

Up to 5,000 m 860 Vrms, verified by a 5 s

dielectric withstand test

Measurement Category I is for measurements performed on
circuits not directly connected to the electrical distribution system
referred to as MAINS voltage. MAINS is a hazardous live
electrical supply system that powers equipment. This category is
for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special
equipment, limited-energy parts of equipment, circuits powered
by regulated low-voltage sources, and electronics.

Caution Do not connect the NI 9216 with DSUB to

signals or use for measurements within Measurement
Categories II, III, or IV.

Note Measurement Categories CAT I and CAT O are

equivalent. These test and measurement circuits are not
intended for direct connection to the MAINS building
installations of Measurement Categories CAT II,
CAT III, or CAT IV.

Safety Guidelines for Hazardous Locations

The NI 9216 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
