Function:
The IUC-7X-TXX is an isolated Thermocouple
transmitter that provides high isolation and rugged
design for many control applications.
Three-way
isolation is provided between the input, the output and
the power. The signal isolation takes place through
state-of-the-art optical isolators to ensure high
accuracy and repeatability.
Special output drive
circuitry allows the IUC-7X-TXX to drive loads of up to
1600 Ohms which makes it ideal for driving multi
instrument loops.
Several standard Thermocouple types and ranges are
available that cover a wide spectrum of temperatures.
Special ranges are available upon consultation with the
factory or your representative.
Calibration:
Calibration is via easily accessible multi-turn
potentiometers.. All instruments are shipped fully
calibrated and tested, but can easily be field adjusted.
A Zero and Span pot are available on all units to adjust
the output signal.
