MODEL 275 HART COMMUNICATOR AND
MODEL 375 FIELD COMMUNICATOR

Many procedures, screens, and wiring diagrams shown in this manual feature the Model 275 HART
Communicator.

The Model 375 Field Communicator is now available. Procedures and screens are similar to those for the
Model 275, however, there are significant differences and an online Configuration Map for use with the
Model 375 is provided at the back of this manual.

Transmitter model and firmware version can affect the displays, display options, and Configuration Maps.

Whether using the Model 275 or the Model 375, be sure to read the manual supplied by the manufacturer
before installing or using the device. Refer to the devices nameplate for hazardous area certifications and
approvals and other important information.
