More Information

Overview Manuals Voltage Loops Calibration Lifecycle Review Application
  • Provides six individually isolated voltage analog output channels
  • Supports configured signal scaling within the documented ±10.5 V range
  • Requires lifecycle review because the complete model is discontinued

1756-OF6VI is a discontinued Allen-Bradley ControlLogix six-point isolated voltage analog output module.

It is used where the engineered ControlLogix application requires isolated voltage outputs and preserved channel scaling.

Verify the loop documentation, configured ranges, calibration records, wiring, and lifecycle plan before replacement.

Availability, condition, price, and shipping time for 1756-OF6VI are confirmed during quotation.

  • Match the receiving instrument to the documented voltage-output function
  • Preserve configured channel scaling during controller or module replacement
  • Verify polarity and signal reference at the field device
  • Use approved calibration records for each installed output loop
  • Review mode and calibration indicators before returning a channel to service
  • Confirm process response in a controlled operating condition
  • Recognize that Rockwell Automation lists this complete model as discontinued
  • Do not assume a different analog module is electrically or project compatible
  • Document any approved migration choice against the installed system
  • ControlLogix voltage analog signal loops with individual channel isolation
  • Process-command outputs requiring configured voltage scaling
  • Six-channel voltage output sections of compatible ControlLogix systems
Description
1756-OF6VI is a discontinued Allen-Bradley ControlLogix six-point individually isolated voltage analog output module.

It provides six ±10.5 V output channels with 250 V continuous isolation between outputs and module-health, calibration, and mode indicators.

Before replacement, preserve the controller project, per-channel ranges and scaling, wiring, calibration records, and process-loop acceptance criteria; do not assume a current-output module is interchangeable.

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.
Can 1756-OF6VI provide current-loop outputs?
No. 1756-OF6VI is a voltage analog output module. Confirm the receiving device and the required signal type before selecting a replacement.
What must be preserved when replacing 1756-OF6VI in a calibrated process loop?
Preserve the controller project, channel scaling, output ranges, field wiring, loop documentation, and accepted calibration records before returning the loop to service.
Why can a 1756-OF6VI replacement produce an incorrect process response with no module fault?
Check the configured range, output scaling, external device input range, channel wiring, and loop calibration. A healthy module does not prove a correct analog signal application.
Can 1756-OF6VI be replaced with any six-point analog output module?
No. The replacement must match the voltage-only function, isolation needs, controller support, wiring, and the existing configured signal behavior.
What does an in-calibration indicator on 1756-OF6VI mean for plant operation?
Treat calibration status as part of controlled maintenance. Follow the site-approved procedure and verify the process effect before releasing a channel to automatic control.
Why is lifecycle review required before sourcing 1756-OF6VI?
Rockwell Automation lists 1756-OF6VI as discontinued. Verify the installed system's support plan and any approved migration strategy rather than assuming a drop-in substitute.
How should unused 1756-OF6VI channels be handled during replacement work?
Retain the approved project configuration and field-circuit treatment for unused channels; do not change signal scaling or wiring merely because the channel is unused.
