Connecting a 3-Conductor HART Sensor

To connect one or two passive 3-conductor HART sensors to the HART module
753-482, a WAGO potential amplification module (item number 753-604 or
753-614) must be connected upstream for the 0 V potential.
The HART+ and HART- sensors are connected to the HART+ and HART-
terminal points of the HART module 753-482. The passive sensors are supplied
with 24 VDC directly from the I/O module.

Connecting Active HART Sensors

To connect active HART sensors to the HART module 753-482, a WAGO
potential amplification module (item number 753-604 or 753-614) is used, as with
the passive 3-conductor HART sensors.
Commensurate with the HART sensor voltage (24 VDC or 230 VAC), the HART
sensors are fed either directly from the potential amplification module with
24 VDC or externally with 230 VAC. In both cases, the potential amplification
module provides the 0 V potential for connecting the HART sensors.
The HART+ sensor is connected to the HART+ terminal point of the HART
module 753-482.
