Output Wiring – Model 2700 FOUNDATION fieldbus and PROFIBUS-PA Transmitters

7.1Overview

This chapter explains how to wire outputs for Model 2700 transmitters with the FOUNDATION fieldbus and PROFIBUS-PA output boards (output option code E, N, or G).

Note: If you don’t know what outputs option board is in your transmitter, see Section 1.4.

It is the user’s responsibility to verify that the specific installation meets the local and national safety requirements and electrical codes.

7.2FOUNDATION fieldbus wiring

Wire the transmitter to the fieldbus segment according to the diagram in Figure 7-1.Follow all local safety regulations. The transmitter is either FISCO or FNICO approved (see Section A.1.1). For FISCO-approved transmitters, a barrier is required. Refer to the FOUNDATION fieldbus wiring specification.
