ITC-XX: Isolated Terminal Signal Conditioner/Converter
Function:
The ITC-XX 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-XX right next to the instrument that is to be isolated. The many
different input and output configurations allow it to be used is a great
variety of applications ranging from PLC front end conditioning to adding an
extra loop with lots of drive to an existing almost fully loaded, loop.
The high output drive (100 Ohms @ 4-20 mA) allows the ITC-XX to drive
several other intruments directly from its output. The standard two wire
supply allows the ITC-XX to be used with two wire field transmitters such as
differential pressure transducers, temperature sensors, etc.
