Overview

The ABB RXFILTER P4RX (1KHL001356R0001) is a high-reliability EMI filtering and signal conditioning module designed for use in high-voltage and industrial automation systems. Its primary function is to attenuate noise on power lines and secure stable digital communication, especially when data and power share the same electrical path.

This module is widely deployed alongside motor protection relays, PLCs, and digital communication devices to safeguard system integrity and reduce unplanned downtime. Built with a compact and rugged construction, the RXFILTER P4RX performs reliably across global industrial environments.

For example, in a substation or MCC, the module filters harmonics and transient disturbances from power conductors — ensuring accurate relay logic and uninterrupted data exchange.
