The ITC-XX-120 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-120 right next to the instrument that is to be isolated. The many different input and output configurations allow it to be used in 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 (1000 Ohms @ 4-20 mA) allows the ITC-XX-120 to drive several other instruments directly from its output. The standard two wire supply allows the ITC-XX-120 to be used with two wire field transmitters such as differential pressure transducers, temperature sensors, etc.
