Introduction

Industrial communication hardware remains important in facilities where established automation systems continue to support production, utilities, and process operations. The ABB TC625 3BSE002224R1 AF100 Coaxial Modem is a model to consider when identifying communication equipment associated with ABB AF100 installations.

For maintenance engineers and industrial spare-parts buyers, selecting the correct communication component involves more than matching a product family. The exact order number, network architecture, interface requirements, and hardware configuration must also align with the installed system.

The TC625 is relevant to maintenance activities involving compatible AF100 infrastructure, particularly where retaining the existing network design is preferable to introducing broader system changes. Accurate product identification helps streamline procurement and provides a clear starting point for technical verification.

When sourcing this modem, buyers should confirm the precise model designation and installation requirements before ordering. This approach supports informed purchasing decisions and helps reduce the risk of compatibility issues during maintenance or replacement.
