Section 1.6
System
Overview
The module communicates to the controller via a 1734 Control Net, Device Net,
or Ethernet adapter. The module receives 5 and 24 VDC power through the bus
interface.
1.6.1 Module Power-up
At power-up, the module performs a check of its internal circuits, memory, and
basic functions. 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 will
generate a PLC fault. Once a channel is properly configured and enabled, it
continuously converts the input data to a value within the range selected for that
channel.
1.6.2 Module Operation
The 1734sc-IF4U module provides four, independent, analog input channels.
Each channel includes four selectable filter settings, and can be configured for
voltage, thermocouple, current, resistance or RTD input types.
The 1734sc-IF4U module uses a 20-bit Sigma-Delta ADC (Analog-to-Digital
Converter) to achieve 18-bit resolution. (This may be limited to 16-bits resolution
by backplane communication.) Inputs to the ADC are first multiplexed through
analog switches, and then buffered by a precision, low offset and drift,
programmable gain amplifier. The ADC also provides the programmable current
source used in resistive measurements.
The 1734sc-IF4U plug-in module communicates over its isolated CAN Bus
interface through the module backplane. The 1734 network adapter then
communicates to the PLC controller.

non-hazardous locations only. The following WARNING statement applies to
use in hazardous locations.
EXPLOSION HAZARD
• Substitution of components may impair suitability for Class I,
Division 2.
• Do not replace components or disconnect equipment unless power
has been switched off or the area is known to be non-hazardous.
Touch a grounded object to discharge static potential.
• Do not connect or disconnect components unless power has been
switched off or the area is known to be non-hazardous.
• This product must be installed in an IP54 rated enclosure.
• All wiring must comply with N.E.C. article 501-4(b).

Chapter 2: Installation and Wiring 2-3
User’s Manual Pub. 0300266-02 Rev. B
2.3.1 Prevent Electrostatic Discharge
Electrostatic discharge can damage integrated circuits or semiconductors if
you touch analog I/O module bus connector pins or the terminal block on
the input module. Follow these guidelines when you handle the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
Remove power before removing or inserting this module. When you
remove, or insert, a module with power applied, an electrical arc may
occur. An electrical arc can cause personal injury or property damage by:
• Sending an erroneous signal to your system’s field devices,
causing unintended machine motion.
• Causing an explosion in a hazardous environment.
• Electric arcing causes excessive wear to contacts on both the
module and its mating connector, and may lead to premature
failure.
2.3.3 Selecting a Location
Reducing Noise
Most applications require installation in an industrial enclosure to reduce the
effects of electrical interference. Analog inputs are highly susceptible to
electrical noise. Electrical noise coupled to the analog inputs will reduce the
performance (accuracy) of the module. Group your modules to minimize adverse
effects from radiated electrical noise and heat. Consider the following conditions
when selecting a location for the analog module. Position the module:
• Away from sources of electrical noise such as hard-contact switches,
relays, and AC motor drives.
• Away from modules which generate significant radiated heat. Refer to
the module’s heat dissipation specification.
In addition, route shielded, twisted-pair, analog input wiring away from any high
voltage I/O wiring.

SURROUNDING AMBIENT TEMPERATURE.
UTILISER DES FILS D’ALIMENTATION QUI CONVIENNENT A
UNE TEMPERATURE DE 20 °C AU-DESSUS DE LA
TEMPERATURE AMBIANTE.
• 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.
• Under normal conditions, the drain wire (shield) should be connected to
the metal mounting panel (earth ground). Keep shield connection to earth
ground as short as possible.
• Ground the shield drain wire at one end only. The typical location is as
follows:
- For grounded thermocouples or millivolt sensors, this is at the
sensor end.
- For insulated/ungrounded thermocouples, this is at the module
end. Contact your sensor manufacturer for additional details.
• Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-
Bradley publication 1770-4.1, for additional information.
Noise Prevention
• Route field wiring away from any other wiring and 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 120 V 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.
• If noise persists for a device, try grounding the opposite end of the cable
shield or ground both ends of the shield.

The IF4U module is not compatible with the 1734-ADN, ADN(X), and
PDN device net adapters, and the 1734-APB PROFIBUS adapter.
The 1734sc-IF4U is not field upgradable.
The ControlNet adapter (1734-ACNR) has a maximum data transmit limit
of 600 bytes. Therefore, the maximum number of 1734sc-IF4U modules
that can be installed behind a ControlNet adapter is 14. The maximum
number of modules that can be installed behind an EtherNet adapter
(1734-AENT) is 19.
Section 3.3
Use Generic
Profile
The generic point IO module profile can be used to represent the IF4U module
within RSLogix 5000. The generic profile should be used for RSLogix 5000
versions 14 and older. Before the generic profile can be added to the IO
configuration, the proper communication module needs to be added to the IO
configuration first. To add a communication module to RSLogix 5000:
1. Add the new local communication module to your project.
2. Configure the local module, including:
a. Naming the module.
b. Choosing a Communication Format.
c. Setting the Revision level.
d. Setting the module location as necessary such as the slot number
for a 1756-CNB module.
e. Choosing an Electronic Keying method.
3. Add the new remote module to your project, such as a 1734 Control Net
adapter or Ethernet Adapter (that is, 1734-ACNR or 1734-AENT,
respectively).
4. Configure the remote module similarly to the local module.
5. Download the configuration to the controller.
If you are using Control Net, you must schedule the network using
RSNetworks for Control Net after adding the local and remote
communication modules.

When you create a new RSLogix 5000 project with the CompactLogix
1769-L32C or L35CR controller, the Controller Organizer creates a
Control Net port in the local chassis. In this case, you do not need to add a
separate, local communication module.

Channel Disable (Bit 0)
Enable (Default) = 0, Disable = 1. If the channel is disabled, all other fields are
ignored.
Filter Frequency (Bits 1 and 2)
The filter selection affects how the module attenuates the input signal at the
specified frequency. It also affects the update time of the input data which is
reflected in the minimum conversion time for each channel. Lower filter
frequencies are recommended for RTD and Thermocouple modes. The total
update time for the module can be calculated using the table below. Default
setting is 17 Hz.

= Sum of conversion times for each
enabled channel
Example:
Channels 0/1 are configured for 3-wire RTD and 4 Hz filter:
Channel 2 is configured for 17 Hz voltage.
Channel 3 is configured for 62 Hz current.
The RTD channel pair has a conversion time of 1024 ms (512*2).
The module scan time will be 1024+153+62 = 1239 ms
3.5.2 RTD Accuracy
The RTD Algorithms used have a curve-fit accuracy that is generally within two
to three decimal places of a degree C across the span of measured resistance
ranges. This conversion accuracy has little effect on the final result. RTD
conversion is therefore heavily dependent on its ability to accurately measure
resistance.
CJC Disable (Bit 3)
When this bit is set, no CJC compensation is applied to the channel if it is
configured as a thermocouple. Default setting is enabled.
Open Circuit Response (Bits 4 and 5)
The open circuit response defines the state of the channel data when an open-
The module update time is purely the sum of the conversion times for each enabled channel except
when a channel is configured for a 3-wire RTD. For each channel configured for a 3-wire RTD, double
the conversion time.

circuit or short-circuit condition is detected. Default setting is upscale.
Sets the input data value to full-scale value. The full-scale
value is determined by the selected input type and data
format.
Sets the input data value to minimum-scale value. The
minimum-scale value is determined by the selected input
type and data format.
Sets the input data value to zero (0).
Input Type (Bits 6 through 10)
These bits specify the input type for each channel. If channel 0 or 2 is configured
for multi-wire RTD, the configuration for the adjacent odd channel (1, 3) is
ignored. It is recommended to configure both channels identically (0 and 1, 2,
and 3) when using multi-wire RTD. This reduces confusion in the setup. A zero
will be reported for the adjacent odd channel in multi-wire RTD. The ±10 V
range is the default input type for each IF4U channel.
Data Format (Bits 11 and 12)
Data Format dictates how the data is presented. Engineering Units ×1 is the
default.

These bits are used for RTD and Resistance modes only. They are used to specify
2-, 3-, or 4-wire RTD modes. This setting is ignored for non-resistance/RTD
input types. Default setting is 3-wire.
Temperature Scale (Bit 15)
Set to 1 to display degrees Fahrenheit. Otherwise 0 displays temperature in
degrees Celsius (default). This field is ignored for non-temperature ranges.

Read Input
Data
The input data file contains module status information and analog input data for
each of the input channels. Analog input data is read for each channel, converted
to a scaled digital value, and stored in the input tags. The input tags for the IF4U
are located under the controller tags. The following examples describe the tag
structure allocated by the Generic Module profile and the AOP.
