and PROFIBUS-PA Transmitters
7.1 Overview
This chapter explains how to wire outputs for Model 2700 transmitters with the F
OUNDATION 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
