- 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.
