More Information

Overview Manuals Analog Channels Power and Noise Loop Commissioning Application
  • Combines four analog input channels and two analog output channels in one FLEX I/O module
  • Uses single-ended, nonisolated channels for distributed measurement and analog command signals
  • Input channels support selectable 0…20 mA, 4…20 mA, 0…10 V, and ±10 V ranges

1794-IE4XOE2 places measurement and analog command functions together at one distributed FLEX I/O node.

The mixed channel arrangement can reduce module count when a machine needs several analog feedback signals and two analog references at the same location.

Treat input power, output power, shielding, signal returns, ranges, and loads as separate checks during design and commissioning.

Availability, condition, price, and shipping time for 1794-IE4XOE2 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.

  • Four single-ended inputs and two single-ended outputs share one FLEX I/O module.
  • Supported channels can be configured for documented voltage or current ranges.
  • Input and output wiring must follow the separate terminal assignments in the manual.
  • Provide the documented external 24 V DC field supply for analog circuitry.
  • Route analog and digital power separately where required to reduce coupled noise.
  • Terminate cable shields and signal returns according to the official wiring diagrams.
  • Confirm each configured range before connecting a transmitter or command load.
  • Check current-loop resistance and voltage-output current against official limits.
  • Validate raw counts, scaling, direction, and fault response from the controller project.
  • Combined acquisition of analog process measurements and generation of two analog command signals.
  • Distributed voltage or current interfacing for machines using a FLEX I/O adapter.
  • Mixed analog stations that require four feedback channels and two actuator-reference channels.
Description
Allen-Bradley 1794-IE4XOE2 combines four nonisolated analog inputs with two nonisolated analog outputs in one FLEX I/O module.

The input and output channels support selectable 0…20 mA, 4…20 mA, 0…10 V, or ±10 V operation, with channel data exchanged through the FLEX I/O adapter.

Before use, verify Series B identity, terminal-base compatibility, range selection, external 24 V DC power, shielded wiring, grounding, load limits, and the saved I/O configuration.

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 Allen-Bradley 1794-IE4XOE2 replace a separate input module and output module?
It can combine four compatible analog inputs and two analog outputs at one slot, but the controller profile, ranges, terminal wiring, power, resolution, and channel behavior must match the existing application.
Can existing field wiring be reused when replacing Allen-Bradley 1794-IE4XOE2?
Only after confirming the installed terminal base is compatible and every input, output, common, shield, and external supply connection matches the documented channel configuration. Record the wiring before removing the original module.
Why should the analog and digital supplies be reviewed for Allen-Bradley 1794-IE4XOE2?
The installation instructions recommend separating analog and digital power to reduce noise. Confirm supply routing, commons, shields, grounding, and ripple before commissioning precision signals.
What must be saved before replacing Allen-Bradley 1794-IE4XOE2?
Record each input and output range, scaling, fault behavior, filter or configuration words, terminal assignments, loop power, output loads, and the controller I/O image.
Why might an Allen-Bradley 1794-IE4XOE2 current output fail to drive its load?
Check range selection, loop continuity, external 24 V DC power, output common, terminal assignment, and whether the total loop resistance stays within the documented current-output load range.
Can voltage and current channels be mixed on Allen-Bradley 1794-IE4XOE2?
The module provides selectable channel ranges, so a project can use supported voltage and current modes. Verify every channel’s configuration and wiring before energizing the field circuit.
What is the principal replacement risk for Allen-Bradley 1794-IE4XOE2?
A module can fit physically while range words, scaling, external power, shield connections, output loading, or controller profile differ, causing inaccurate readings or unsafe commands.
