Overview Manuals Protocol Use Power & Storage Safety Limits Applications

Features:

  • Supports field maintenance communication with supported HART and FOUNDATION fieldbus devices.
  • Separate HART and fieldbus terminal pairs keep the two connection paths distinct.
  • Removable power, System Card, and expansion options define the installed unit configuration.
The handheld combines its display, keypad, protocol applications, and physical terminals in one portable field-service platform.

The complete label and installed option set identify the exact communicator configuration, including the certification boundary for hazardous-area work.

After maintenance, a normal startup and a communication test confirm that the power assembly, System Card, and selected protocol path are functioning together.

  • Select the HART or FOUNDATION fieldbus application before choosing the physical terminal pair.
  • Use the dedicated HART terminals for supported HART device communication and loop service.
  • Confirm available segment current before attaching the communicator to an active FOUNDATION fieldbus segment.
  • Complete a communication check with the intended device before the field task is released.
  • Identify whether the unit uses a NiMH Battery Pack or Lithium Ion Power Module.
  • Match the charger to the installed removable power component and approved accessory configuration.
  • Handle the System Card under the documented power-down procedure and protect its contacts from static and contamination.
  • Use the expansion port only with options supported for the installed communicator configuration.
  • Treat the certification label on the exact communicator as the boundary for intrinsically safe use.
  • Apply the hazardous-area requirements of the site and the connected instrument segment.
  • Do not infer an approval from enclosure appearance or from another unit in the 375 family.
  • Match power and communication accessories to the approved configuration before hazardous-area service.
  • Configuration and maintenance communication with supported HART field devices.
  • FOUNDATION fieldbus device service on segments that meet the connection-current and site-procedure requirements.
  • Legacy instrument troubleshooting where protocol selection and terminal separation are important.
  • Bench verification after power-module, System Card, or approved accessory service.
Description
375 Field Communicator gives field technicians one handheld interface for supported HART and FOUNDATION fieldbus devices, combining the display, keypad, protocol terminals, removable power, and System Card in a service platform.

375 Field Communicator configuration matters when a legacy unit is replaced: the certification label, installed power assembly, System Card, and optional hardware determine what can be reused safely.

375 Field Communicator separates HART and fieldbus connections, helping technicians keep the selected protocol and terminal path clear while working on an installed instrument segment.
Alternative Names
HART 375
Technical notes
The 375 Field Communicator uses separate terminal pairs for HART and FOUNDATION fieldbus work, and intrinsically safe use depends on the certification fitted to the exact unit. Selecting the wrong terminal, power assembly, or System Card can invalidate the service setup, so those items must match the installed communicator before field use.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When sourcing a 375 Field Communicator, which details distinguish the required configuration?
Use the complete main-unit label, installed option set, certification marking, power assembly, and System Card identity. Stop the purchase review if any of those details cannot be matched to the installed unit.
Can a 375 Field Communicator be selected for a hazardous area from enclosure appearance alone?
No. Intrinsically safe use depends on the certification fitted to the exact communicator and the site hazardous-area rules; appearance or another unit's approval is not sufficient.
What must a technician establish before connecting a 375 Field Communicator to an active fieldbus segment?
Use the fieldbus terminal pair, confirm that the segment has the required available current, and follow the site's live-segment connection procedure before making the connection.
Can any charger be used with a 375 Field Communicator during bench service?
No. Match the charger to the installed NiMH Battery Pack or Lithium Ion Power Module and to the approved accessory configuration for that communicator.
How should a 375 Field Communicator System Card be handled during maintenance?
Follow the documented power-down sequence, protect the card and contacts from contamination and static damage, and reinstall it securely in the correct slot before startup.
What result should release a serviced 375 Field Communicator back to field use?
Normal startup to the main menu and successful communication with an approved test device should both be demonstrated after the power assembly, System Card, and terminals are checked.
