General Safety Information

WARNING

• Do not use the device if it is damaged. Before you use the device,

inspect the case. Look for cracks or missing plastic. Do not operate the

device around explosive gas, vapor or dust.

• Do not apply more than the rated voltage (as marked on the device)

between terminals, or between terminal and external ground.

• Always use the device with the cables provided.

• Observe all markings on the device before connecting to the device.

• Turn off the device and application system power before connecting to

the I/O terminals.

• When servicing the device, use only specified replacement parts.

• Do not operate the device with the removable cover removed or

loosened.

• Do not connect any cables and terminal block prior to performing

self-test process.

• Use only the power adapter supplied by the manufacturer to avoid any

unexpected hazards.

CAUTION

• Do not load the input and output terminals above the specified

operating limits. Input terminals should not exceed ±10 V with respect

to the module ground. Applying excessive voltage or overloading the

device will cause irreversible damage to the circuitry.

• Applying excessive voltage or overloading the input terminal will

damage the device permanently.

• If the device is used in a manner not specified by the manufacturer, the

protection provided by the device may be impaired.

• The U2802A can only be used with U2355A or U2356A DAQs and used

with the SCSI cables provided.

• Always use dry cloth to clean the device. Do not use ethyl alcohol or

any other volatile liquid to clean the device.

• Do not permit any blockage of the ventilation holes of the device.

2 Agilent U2802A 31-Channel Thermocouple Input User’s Guide

Introduction to Agilent U2802A 31-Channel Thermocouple Input

The Agilent U2802A 31- channel thermocouple input is a thermocouple

input device that functions to convert low input voltage signal

(< ±100 mV) from a thermocouple into an output voltage range suitable for

data acquisition (DAQ) device (± 10 V).

The Agilent U2802A thermocouple signal conditioner is to be used in

conjunction with the U2355A or U2356A model DAQ to enable

temperature measurements using thermocouples.

It works as a standalone device attached to a single DAQ. The U2802A

thermocouple device is connected to the modular DAQ via SCSI cables.

Agilent U2802A accepts eight standard thermocouple types defined in the

NIST ITS-90 Thermocouple Database, which are Type B, E, J, K, N, R, S

and T.

It is ideal for a broad variety of temperature and voltage measurement

applications in education, industrial and scientific environments. The

U2802A comes with an on-board EEPROM features. Hence, it allows user

to store calibration data in volatile memory. Therefore, the U2802A is

robust, cost- effective, and user friendly device.

For detailed product specifications, please refer to “General Specifications”

on page 48.
