Chapter 1
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
•An overview of the system and module operation
Section 1.1
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.

Section 1.3
Filter
Frequencies The module uses a digital filter that provides high frequency noise rejection for the input
signals. The filter is programmable, allowing you to select from five different filter
frequencies for each channel:
•28.5 Hz
•50 Hz
•60 Hz
•300 Hz
•360 Hz
Section 1.4
Hardware
Features The module contains a removable terminal block. Channels are wired as differential
inputs (i.e. each channel will have a dedicated ground).
Note: A jumper must be installed on the terminal block between CH- and CH-iRtn for
all current input ranges.
Module configuration is done via the controller’s programming software. In addition,
some controllers support configuration via the user program. In either case, the module
configuration is stored in the memory of the controller. Refer to your controller’s user
manual for more information. The illustration below shows the module’s hardware
features.

1.4.1 General Diagnostic Features
The module contains a diagnostic LED that helps you identify the source of problems that
may occur during power-up or during normal channel operation. The LED indicates both
status and power. Power-up and channel diagnostics are explained in Chapter 9
Diagnostics and Troubleshooting.
Section 1.5
System
Overview The modules communicate to the controller through the bus interface. The modules also
receive 5 and 24V dc power through the bus interface.
1.5.1 System Operation
At power-up, the module performs a check of its internal circuits, memory, and basic
functions. During this time, the module status LED remains off. If no faults are found
during power-up diagnostics, the module status LED is turned on.
After power-up checks are complete, the module waits for valid channel configuration
data. If an invalid configuration is detected, the module generates a configuration error.
Once a channel is properly configured and enabled, it continuously converts the input
data to a value within the range selected for that channel.
Each time a channel is read by the input module, that data value is tested by the module
for an over-range, under-range, open-circuit, or “input data not valid” condition. If such a
condition is detected, a unique bit is set in the channel status word. The channel status
word is described in Section 6.3 Input Data File.
Using the module image table, the controller reads the two’s complement binary
converted input data from the module. This typically occurs at the end of the program
scan or when commanded by the control program. If the controller and the module
determine that the data transfer has been made without error, the data is used in the
control program.

Compact™ IO Isolated HART Analog Input Module
User's Manual 0300215-03 Rev. A

Section 1.6
Module
Operation When the module receives the input from an analog device, the module’s circuitry
multiplexes the input into an A/D converter. The converter reads the signal and converts
it as required for the type of input. If HART is enabled on a channel, the HART data is
acquired my means of an onboard HART modem.
Note: The HART data is acquired asynchronously from the analog acquisition process
and therefore does not directly effect the analog update time.
See the block diagram below.
Figure 1-2
The module is designed to support up to 4 isolated channels which can be independently
configured for voltage, current, or current with HART. The module converts the analog
values directly into digital counts which are viewed and accessed from within the PLC
via controller input tags.
The HART data, if enabled, is converted directly to a block of twenty controller input
tags. The data within this block of twenty tags is multiplexed. For information on HART
and how to demultiplex the HART data, refer to Chapter 7.

Quick Start for Experienced
Users
Section 2.1
Before
You Begin This chapter can help you get started using the 1769sc-IF4IH isolated HART analog
input module. We base the procedures here on the assumption that you have an
understanding of Allen-Bradley controllers. You should understand electronic process
control and be able to interpret the ladder logic instructions required to generate the
electronic signals that control your application.
Because it is a start-up guide for experienced users, this chapter does not contain detailed
explanations about the procedures listed. It does, however, reference other chapters in
this book where you can get more information about applying the procedures described in
each step.
If you have any questions or are unfamiliar with the terms used or concepts presented in
the procedural steps, always read the referenced chapters and other recommended
documentation before trying to apply the information.

5. To allow communication between the controller and module, move the bus lever
fully to the left (4) until it clicks. Ensure it is locked firmly in place.
6. Attach an end cap terminator (5) to the last module in the system by using the
tongue-and-groove slots as before.
7. Lock the end cap bus terminator (6).
!
Attention
When attaching I/O modules it is very important that the bus connectors
are securely locked together to ensure proper electrical connection.
!
Attention
A 1769-ECR or 1769-ECL right or left end cap respectively must be used
to terminate the end of the 1769 communication bus.
Step 3: Wire the module. Reference
Chapter 3 (Installation and Wiring)
Follow the guidelines below when wiring the module.
General
•Power and input wiring must be in accordance with Class 1, Division 2 wiring
methods, Article 501-4(b) of the National Electric Code, NFPA 70, and in
accordance with the authority having jurisdiction.
•Channels are isolated from one another by ±500V dc maximum.
•Route field wiring away from any other wiring and keep it as far as possible from
sources of electrical noise, such as motors, transformers, contactors, and ac devices.
As a general rule, allow at least 15.2 cm (6 in.) of separation for every 120V of
power.
•Routing field wiring in a grounded conduit can reduce electrical noise.
•If field wiring must cross ac or power cables, ensure that they cross at right angles.
Terminal Block
•For voltage and current sensors, use Belden 8761 shielded, twisted-pair wire (or
equivalent) to ensure proper operation and high immunity to electrical noise.
•To ensure optimum accuracy, limit overall cable impedance by keeping a cable as
short as possible. Locate the module as close to input devices as the application
permits.
Grounding
•This product is intended to be mounted to a well-grounded mounting surface such as
a metal panel. Additional grounding connections from the module’s mounting tabs or
DIN rail (if used) are not required unless the mounting surface cannot be grounded.
•Keep cable shield connections to ground as short as possible.
•Ground the shield drain wire at one end only. The preferred location is as follows.
•Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-4.1, for additional information.

check if the module is operating
correctly Reference
Chapter 9 (Diagnostics and
Troubleshooting)
Module and channel configuration errors are reported to the controller. These errors are
typically reported in the controller’s I/O status file. Channel status data is also reported in
the module’s input data table, so these bits can be used in your control program to flag a
channel error.
