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 24V dc power through the bus interface.
User’s Manual Pub. 0300266-01 Rev. A
Chapter 1: Module Overview |
1-5 |
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 utilizes a 20-bit Sigma-Delta ADC (Analog to Digital Converter) to achieve 18-bit resolution. Inputs to the ADC are first multiplexed through analog switches 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. See the block diagram below.

Section 2.1 Compliance to European Union Directives
This product is approved for installation within the European Union and EEA regions. It has been designed and tested to meet the following directives.
2.1.1 EMC Directive
The 1734sc-IF4U module is tested to meet Council Directive 89/336/EEC Electromagnetic Compatibility (EMC) and the following standards, in whole or in part, documented in a technical construction file:
IEC 61000-6-4 Electromagnetic compatibility (EMC) - Part 6-4: Generic standards - Emission standard for industrial environments
IEC 61000-6-2 Electromagnetic compatibility (EMC) – Part 6-2: Generic standards – Immunity for industrial environments
This product is intended for use in an industrial environment.
2.1.2 Low Voltage Directive
This product is tested to meet Council Directive 73/23/EEC Low Voltage, by applying the safety requirements of EN 61131-2Programmable Controllers, Part 2 – Equipment Requirements and Tests. For specific information required by EN61131-2, see the appropriate sections in this publication, as well as the following Allen-Bradley publications:
Industrial Automation, Wiring and Grounding Guidelines for Noise Immunity, publication 1770-4.1
Automation Systems Catalog, publication B113
Section 2.2 Power Requirements
The module receives power through the bus interface from the +5V dc/+24V dc system power supply. The maximum current drawn by the module is shown in the table below.

Use the table below to determine the maximum number of IF4U modules that can be installed in a MicroLogix system.
Section 2.3 General Considerations
1734 I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments Pollution degree 21 and to circuits not exceeding Over Voltage Category II2(IEC 60664-1)3.
2.3.1 Hazardous Location Considerations
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or nonhazardous locations only. The following WARNING statement applies to use in hazardous locations.
!
Attention
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 nonhazardous.
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).
1Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a temporary conductivity caused by condensation shall be expected.
2Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.
3Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
User’s Manual Pub. 0300266-01 Rev. A
Chapter 2: Installation and Wiring |
2-3 |
2.3.2 Prevent Electrostatic Discharge
!
Attention
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 the bus connector or connector pins.
Do not touch circuit components inside the module.
If available, use a static-safe work station.
When it is not in use, keep the module in its static-shield bag.
2.3.3 Remove Power
!
Attention
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
Electrical arcing causes excessive wear to contacts on both the module and its mating connector and may lead to premature failure.
2.3.4 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.
Section 2.4
Mounting
2.4.1 Before You Begin
Note that this series C product can be used with the following:
ControlNet and EtherNet/IP adapters ONLY, using RSLogix 5000 software, version 11 or later
