More Information

Overview Manuals Wiring Filtering Isolation Application
  • ControlLogix analog input module for both voltage and current field signals
  • Documented single-ended and differential wiring methods support different signal applications
  • Module configuration includes a common real-time sample and selectable digital filtering

1756-IF16 converts field voltage or current signals for use by a ControlLogix controller project.

The selected wiring method, field grounding, signal source, removable terminal block, and project configuration must be treated as one installation.

Before replacement, record the module Series, RTB, channel assignments, input mode, sampling, filtering, alarms, controller firmware, and wiring.

Availability, condition, price, and shipping time for 1756-IF16 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Rockwell Automation documents single-ended voltage and current wiring
  • Differential voltage and current wiring are documented for suitable signal applications
  • 1756-TBCH and 1756-TBS6H are the listed removable terminal-block options
  • One real-time sample setting applies to the complete module
  • The selected digital filter attenuates the configured frequency
  • The digital filter also attenuates harmonics of the selected frequency
  • Inputs are isolated from the backplane by reinforced insulation
  • The documented continuous isolation voltage is 250 V
  • Channel-to-channel isolation is not provided
  • ControlLogix systems acquiring multiple voltage or current process signals
  • Applications requiring a documented choice of single-ended or differential field wiring
  • Analog input replacement projects where RTB, wiring, Series, and project settings must be preserved
Description
1756-IF16 is an Allen-Bradley ControlLogix 16-point analog input module for voltage and current signals.

The module accepts -10...+10 V and 0...20 mA inputs, supports documented single-ended and differential wiring methods, and provides reinforced input-to-backplane isolation without channel-to-channel isolation.

Before installation or replacement, verify the field-signal type, wiring method, removable terminal block, sampling and filter settings, module Series, controller project, grounding, and enclosure requirements.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Should Allen-Bradley 1756-IF16 be wired as single-ended or differential input?
Use the Rockwell Automation wiring method that matches the signal source, grounding, noise environment, required channel arrangement, and project configuration.
Which removable terminal block fits Allen-Bradley 1756-IF16?
Rockwell Automation lists 1756-TBCH and 1756-TBS6H as the removable terminal-block options; verify the installed wiring style before ordering.
Does Allen-Bradley 1756-IF16 isolate every channel from the others?
No. The module provides reinforced isolation between the inputs and backplane, but Rockwell Automation specifies no channel-to-channel isolation.
How do the real-time sample and digital filter work on Allen-Bradley 1756-IF16?
One real-time sample setting applies to the whole module, and the selected digital filter attenuates the chosen frequency and its harmonics.
What should be checked when replacing Allen-Bradley 1756-IF16 Series A with Series B?
Compare the module Series, controller firmware, Add-On Profile/module definition, keying, wiring mode, RTB, channel configuration, sample rate, filters, and alarm settings.
What can cause unstable readings on Allen-Bradley 1756-IF16?
Check signal grounding, cable shielding, source impedance, single-ended versus differential wiring, filter selection, sample rate, field power, and channel configuration against the official wiring diagrams.
Which official information should accompany an Allen-Bradley 1756-IF16 replacement request?
Provide the complete catalog number, nameplate Series, RTB type, wiring method, controller and firmware, signal ranges, channel configuration, and clear label photographs.
