ITC-7X-TXX: Isolated Thermocouple Signal Conditioner/Converter
Function:
The ITC-7X-TXX provides high isolation from Input to Output to Power in a small, easy to install
package. The universal DIN rail mount often makes it possible to install the ITC-7X-TXX right next
to other instruments that it is to be wired to. The many different Thermocouple types and ranges
as well as output configurations allow it to be used in a great variety of temperature measurement
applications.
The high output drive (1000 Ohms @ 4-20 mA) allows the ITC-7X-TXX to drive several other instruments
directly from its output.
Upscale protection is standard on all units unless downscale protection is specified.
