Module Overview

This chapter describes the 1769sc-IF4IH isolated HART analog input module and
explains how the module reads current, voltage, and current with HART input data.

Included is information about:

The module’s hardware and diagnostic features

General
Description

The IF4IH is a four channel isolated module that allows each channel to be configured
independently for either current, voltage, or current with HART communication. The
module digitally converts and stores analog data from any combination mentioned above
as well as HART data for channels configured for HART. Each input channel is
individually configured via software for a specific input device, data format and filter
frequency, and provides over-range and under-range detection and indication.

The tables below list the input types and their associated ranges.
