Safety Voltages
Connect only voltages that are below these limits.
V terminal to C terminal 30 VDC maximum, Measurement Category I
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 sbRIO-9637 to signals or use for measurements within
Measurement Categories II, III, or IV.
Preparing the Environment
Ensure that the environment in which you are using the sbRIO-9637 meets the following
specifications.
Local ambient operating temperature near
device (IEC 60068-2-1, IEC 60068-2-2)
-40 °C to 85 °C
Maximum reported onboard sensor temperature
CPU/FPGA temperature 98 °C
Primary System temperature 85 °C
Secondary System temperature 85 °C
Note Ensure that the local ambient, reported CPU/FPGA, and reported Primary
System temperatures do not exceed any of the maximum temperatures listed in this
document. For more information about how to access the onboard sensors, visit
ni.com/info and enter the Info Code sbriosensors.
Operating humidity (IEC 60068-2-78) 10% RH to 90% RH, noncondensing
Pollution Degree (IEC 60664) 2
Maximum altitude 5,000 m
Indoor use only.
Note Refer to the device specifications on ni.com/manuals for complete
specifications.
