ControlLogix HART Analog I/O Modules

Introduction

ControlLogix HART analog I/O modules connect a Logix controller to your
process. 1756-IF8H and 1756-IF16H input modules receive the signals from
process value transmitters and convert them to temperature, flow, pressure, pH,
and other measurements for use in the Logix controller. By using 1756-OF8H
HART output modules, the controller adjusts the setting of valves and other
devices to keep your process running as desired.

Using instruments that support the HART protocol allows measuring several
process parameters with a single field device, provides enhanced status and
diagnostics, and allows remote configuration and troubleshooting.

The table explains the topics discussed in this chapter.
