Product Introduction
The ABB P4RX 1KHW001356R0004 is identified as a P4RX RX Filter, indicating a filtering function associated with an RX signal path rather than a programmable PLC or conventional process I/O module. The exact ABB ordering code is important because public records for this part are limited and do not provide enough reliable information to establish universal voltage, current, frequency, or connector specifications.
From a maintenance standpoint, this component should be treated as a system-specific ABB filter assembly. Its electrical behavior depends on the equipment in which it is installed. Replacing it solely on the basis of physical appearance or a generic “RX filter” description can introduce an incorrect impedance, attenuation characteristic, or interface configuration into the signal chain.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
The P4RX 1KHW001356R0004 is most relevant to maintenance of ABB equipment where the filtering stage forms part of an existing signal or control architecture. A filter of this type may be used to suppress unwanted signal components or condition an RX path before the receiving electronics process the signal, but the exact circuit role should be established from the parent equipment drawings rather than inferred from the short product designation.
Field checks before replacement:
- Match the complete part number: Use 1KHW001356R0004, not simply “.”
- Confirm the parent assembly: Identify the ABB cabinet, drive, controller, or power-electronics assembly in which the filter is installed.
- Verify electrical characteristics: Do not assume voltage, current, impedance, attenuation, or frequency specifications without the relevant ABB documentation.
- Check connector orientation and wiring: Filter assemblies can be physically similar while having different electrical characteristics.
- Inspect the surrounding circuit: If the original filter failed, check the upstream transmitter/source and downstream receiver before installing a replacement.
- Record the installed hardware revision: Photograph the label and connector side before removal; revision differences can matter in legacy ABB equipment.
