More Information

Overview Manuals Signal Selection Block Transfer Installation Application
  • Supports eight differential or sixteen single-ended analog input channels
  • Accepts configurable voltage or current signals and exchanges data through block transfers
  • Receives module operating power from the 1771 chassis backplane

1771-IFEK configuration begins with selecting the required differential or single-ended channel arrangement and matching each field signal to the documented voltage or current range.

Confirm the Series C hardware, 1771-WG field-wiring arm, chassis slot and addressing, signal polarity, grounding method, scaling, and PLC-5 block-transfer setup before commissioning the module.

Retain the complete K-suffix catalog number when the installation requires the conformally coated version; substituting a standard 1771-IFE may not provide the same environmental construction.

Availability, condition, price, and shipping time for 1771-IFEK are confirmed during quotation.

Description
1771-IFEK is the conformally coated catalog variant of the Allen-Bradley 1771-IFE analog input module for supported PLC-5 and 1771 I/O installations.

Based on the Series C 1771-IFE platform, the module accommodates eight differential or sixteen single-ended analog inputs. Supported channel configurations include documented voltage and current signal ranges used for process measurement.

Input configuration and measurement data are exchanged with the controller through block transfers. The module receives its operating power from the 1771 chassis backplane and uses the specified 1771-WG field-wiring arm for signal connections.

Before installing or replacing a 1771-IFEK, confirm the complete K-suffix catalog number, hardware series, channel arrangement, signal type and range, wiring-arm compatibility, chassis slot and addressing, grounding method, scaling, and existing PLC-5 block-transfer configuration.

Technical notes
1771-IFEK uses conformal-coated Series C hardware; retain the 1771-WG wiring arm and restore the original input-mode and block-transfer settings to avoid configuration errors.

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.
When is the conformal coating on 1771-IFEK important for a replacement decision?
The K-suffix coating is relevant when the installed module was selected for added protection against contaminants or humidity. Confirm the original environmental requirement instead of substituting an uncoated module by appearance alone.
Can 1771-IFEK be replaced by a standard 1771-IFE?
Do not treat the catalog numbers as automatically interchangeable. Confirm that the application still requires conformal coating and that the Series C input configuration, wiring arm, range, and approvals match.
Can 1771-IFEK reuse an installed 1771-WG field-wiring arm?
It can be retained only after the arm, terminal assignments, channel wiring, connector condition, and chassis keying are verified against the Series C installation documentation.
What PLC changes may be required when installing 1771-IFEK in a different slot?
Moving the module changes its rack, group, or slot relationship. Update and verify the block-transfer instructions, data addresses, channel configuration, and any logic that references its status or input words.
What should be checked if 1771-IFEK produces unstable analog readings after installation?
Review signal range selection, differential or single-ended wiring, shielding, grounding, source impedance, terminal condition, and restored block-transfer configuration before replacing the module again.
Does 1771-IFEK require a separate external module power supply?
The underlying Series C module uses chassis-backplane power rather than a separate module supply. Verify available backplane capacity and keep transmitter or field-loop supplies distinct from module operating power.
What must be preserved before replacing 1771-IFEK?
Save the block-transfer setup, differential or single-ended selection, channel ranges, scaling, alarm behavior, slot assignment, and field wiring, and verify that the replacement retains the required K coating suffix.
