Emerson 475 Field Communicator – HART & FOUNDATION Fieldbus

Overview

The Emerson 475 Field Communicator is the industry-standard handheld for commissioning, configuring, and troubleshooting smart field devices. It supports HART (v5/6/7) and FOUNDATION Fieldbus H1, giving technicians one rugged tool to set ranges, trim sensors, update device parameters, run diagnostics, and capture logs across transmitters, valve positioners, and other intelligent instruments. A bright color display, joystick navigation, and a numeric keypad make field work fast—even with gloves. The 475 uses an updatable DD library (Easy Upgrade) so new device revisions are recognized without sending the unit back to service. A rechargeable battery, USB PC connection, and hazardous-area–approved options complete a dependable, job-site ready communicator.

FAQ

Does the 475 power the loop?

No, the transmitter/loop must be powered. The 475 communicates over the powered loop (or bench-supply).

Can it handle new device revisions?

Yes—update the DD library via Easy Upgrade to support new models/firmware.

Is it intrinsically safe?

Versions with hazardous-area approvals exist. Check your unit’s nameplate or send us a photo for verification.

What about FOUNDATION Fieldbus?

The 475 supports FF H1 for parameterization, checks, and basic diagnostics.
