To connect to a point in the local HART loop:
a. Attach the leads from the signal converter to any point in the loop.
b. Add resistance as necessary to achieve at least one volt across the connection
points.
Important
HART/Bell 202 connections require a voltage drop of 1 VDC. To achieve this, add
resistance of
250–600
Ω
to the connection.
