GETTING STARTED GUIDE
NI 9210
4-Channel, 14 S/s Aggregate, ±80 mV C Series
Temperature Input Module

This document explains how to connect to the NI 9210. In this
document, the NI 9210 with mini-TC and the NI 9210 with
spring terminal are referred to inclusively as the NI 9210.
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 9210. 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 9210 with mini-TC. To prevent damage, use
industry-standard ESD prevention measures during
installation, maintenance, and operation.
Safety Guidelines
Operate the NI 9210 only as described in this document.

Caution This icon denotes a caution, which advises
you to consult documentation where this symbol is
marked.
Caution Do not operate the NI 9210 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

NI 9210 with Mini-TC Safety Voltages
Connect only voltages that are within the following limits:
Isolation
Channel-to-channel None
Channel-to-earth ground
Continuous 60 V DC,
Measurement Category I
Withstand 1,000 V RMS, verified by a 5 s
dielectric withstand test
NI 9210 Getting Started Guide | © National Instruments | 3

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 9210 with mini-TC 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 for
other circuits not intended for direct connection to the
MAINS building installations of Measurement
Categories CAT II, CAT III, or CAT IV.

NI 9210 with Spring Terminal Safety Voltages
Connect only voltages that are within the following limits:
Isolation
Channel-to-channel None
Channel-to-earth ground
Continuous 250 V RMS,
Measurement Category II
Withstand 3,000 V RMS, 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.

Minimizing Thermal Gradients
Changes in the ambient air temperature near the front connector
or a thermocouple wire conducting heat directly to terminal
junctions can cause thermal gradients. Observe the following
guidelines to minimize thermal gradients and improve the system
accuracy.
• Use small-gauge thermocouple wire. Smaller wire transfers
less heat to or from the terminal junction.
• Run thermocouple wiring together near the thermocouple
connector to keep the wires at the same temperature.
• Avoid running thermocouple wires near hot or cold objects.
• Minimize adjacent heat sources and air flow across the
terminals.
• Keep the ambient temperature as stable as possible.
• Make sure the NI 9210 terminals are facing forward or
upward.
• Keep the NI 9210 in a stable and consistent orientation.
• Allow the thermal gradients to settle after a change in system
power or in ambient temperature. A change in system power
NI 9210 Getting Started Guide | © National Instruments | 15

can happen when the system powers on, the system comes
out of sleep mode, or you insert/remove modules.
• If you connect any extension wires to thermocouple wires,
use wires made of the same conductive material as the
thermocouple wires.
NI 9210 Connection Guidelines
• Make sure that devices you connect to the NI 9210 are
compatible with the module specifications.
• For the NI 9210 with spring terminal, push the wire into the
terminal when using a solid wire or a stranded wire with a
ferrule.
• For the NI 9210 with mini-TC, open the terminal by pressing
the push button when using stranded wire without a ferrule.
• For the NI 9210 with mini-TC, press the push button to
remove wires.

NI 9210 with Mini TC COM Connection
Guidelines
Observe the following guidelines when connecting to the COM
terminal.
• You must use 2-wire ferrules to create a secure confecting
when connecting more than one wire to a single terminal.
• Open the terminal by pressing the push button when using
stranded wire without a ferrule.
• Push the wire into the terminal when using a solid wire or a
stranded wire with a ferrule.
Overvoltage Protection
The NI 9210 provides overvoltage protection for each channel.
Note Refer to the device datasheet on ni.com/manuals
for more information about overvoltage protection.
