Working Principle
The FBM18 acts as a digital gateway, communicating directly with smart transmitters via fieldbus protocols. It extracts digital process variables and diagnostic parameters, packages them into redundant fieldbus frames, and transmits them to the control processor.
Installation Requirements
Must be installed on a compatible FBM baseplate. Field wiring requires proper shielded twisted-pair cables to maintain fieldbus signal integrity.
Usage Precautions
Ensure connected field devices are compatible with the Foxboro smart transmitter protocol. Always observe ESD precautions during handling and installation.
