Product Description

Overview

The ABB G4AA (HENF209644R5) is a high-performance P4LTb RF-Converter Control Board designed for the ABB ETL600 Digital Power Line Carrier System (Release 1.0). It integrates a DPLC modem, a Digital Signal Processor (DSP), and a Human-Machine Interface (HMI) into a single compact module. Its primary function is to convert low-frequency (LF) signals into radio-frequency (RF) signals, enabling reliable data transmission across high-voltage power lines used in grid monitoring, protection, and utility communications.

This control board combines signal processing, RF conversion, and system monitoring into one module, reducing cabinet complexity while enhancing signal integrity.

Key Features

Integrated LF-to-RF Conversion
The board performs internal modulation and demodulation, eliminating external converters and maintaining high signal fidelity for mission-critical utility applications.

Advanced DSP Filtering
The onboard Digital Signal Processor reduces noise and interference on power lines, ensuring accurate delivery of tripping signals and other sensitive communications.

LED-Based Diagnostic Indicators
Three front-panel LEDs allow rapid system assessment and troubleshooting without specialized tools: RDY for operational readiness, P4LT for board-level faults, and SYS for cabinet-level alarms.

Flexible Interface and Synchronization
Supports multiple RS-232 ports and IRIG-B for precise GPS-based time synchronization, essential for accurate event logging in grid monitoring systems.

Rugged Industrial Design
Engineered to operate in high-voltage substation environments, the board meets EMC requirements, resists electrical surges, and tolerates extreme temperatures and humidity.

Applications

Power line monitoring and protection systems
Utility grid communication networks
Substation automation and remote control
Integration with ETL600 DPLC systems for industrial telemetry
