U2352A Datasheet, PDF (16/25 Pages) Keysight Technologies – USB Modular Multifunction Data Acquisition Devices

Optional Accessories
The Keysight U2802A is a 31-channel
thermocouple signal conditioning
module with a built-in thermistor
for cold junction compensation.
The U2802A is designed to convert
low input voltage signals (less than
±100 mV) from a thermocouple into
an output voltage range suitable for
data acquisition devices (±10 V).
The U2802A device is to be used in
conjunction with the Keysight U2355A
or U2356A model DAQ device to
enable temperature measurements
using thermocouples. It works as
a standalone device attached to a
single DAQ device via two SCSI-II
68 conductor cables. Designed with
the compatibility to complement
eight standard thermocouple types, it
caters to a wide range of applications
in various industrial settings.
Features to meet your demands
–– 31 input channels that can be independently configured to either differential thermo-
couple input mode, single-ended voltage input mode, or differential voltage input mode
using two input channels set to voltage input mode
–– Supports the standard thermocouple types (J, K, R, S, T, N, E, and B) defined in the
NIST ITS-90 Thermocouple Database
–– Error detection for open thermocouple channels
–– Built-in isothermal construction on terminal block for improved measurement accuracy
–– Built-in thermistor for cold junction compensation
–– Built-in zeroing function to compensate for overall system offset errors due to tem-
perature drift and long term drift
–– Up to ±10 V input voltage range for higher voltage inputs
–– Sampling rate of 500 kSa/s for overall module
–– Sampling rate of 10 kSa/s total for all channels in thermocouple mode
–– Quick and easy USB setup
–– Robust, cost-effective, and user friendly
