Model 1175:    Isolated/Specialized Thermocouple Interface

Datasheet    XIF File

Description

The Model 1175 is an Isolated Thermocouple Network Interface with unique and specialized features.

The Model 1175 has been tested with XCO Corporation’s FTLD and CT2 Continuous Thermocouple sensors.  These are unique sensors that could extend for several hundred feet and measure the highest temperature along their entire length.  The Model 1175 is particularly well suited for use with these sensors due to its excellent performance, very high input impedance, and extremely low input current.   Please visit the www.xco.com website for more information on this product. Finally, the Model 1175’s Thermocouple input is isolated from the DC input power supply.  This allows it to be used with grounded thermocouple as well as non-grounded types.
