ABB TC630 3BSE002253R1 Communication Module

Product Overview

The ABB TC630 (3BSE002253R1) is a high-reliability optical modem designed for the Advant Fieldbus 100 (AF 100) communication network. It functions as a critical interface for converting signals between coaxial and optical media or vice-versa, enabling extended distance communication within the Advant OCS (Open Control System) architecture. Operating on a 24V DC power supply, the TC630 supports fiber optic specifications of 2 x 62.5/125 µm or 100/400 µm, utilizing industry-standard ST-style connectors. This module is primarily deployed in Advant Controller 110, 160, 410, and 450 environments, as well as S800 I/O systems, providing galvanic isolation and noise immunity for long-distance fieldbus segments in power plants and heavy industrial facilities.

Engineering & Installation Guide

Optical Fiber Selection and Link Budget

The TC630 supports two distinct fiber optic core sizes. For standard industrial applications, 62.5/125 µm multi-mode fiber is typical. Ensure that the total optical link budget does not exceed the attenuation limits defined in the Advant Fieldbus 100 User Manual. Exceeding these limits can result in intermittent communication drops or high error rates on the AF 100 bus.

Power Supply and Grounding

The module requires a stable 24V DC source. In distributed control architectures, it is recommended to use a redundant power supply to ensure network availability. While the optical link provides inherent galvanic isolation between bus segments, the coaxial side must be handled according to standard AF 100 grounding rules to prevent ground loops.

Maintenance and Replacement

The TC630 is frequently used in preventive maintenance cycles for Advant Controller 450 and 160 systems. Note that this part is exempted from the scope of 2011/65/EU (RoHS) as per Article 2(4) for specific industrial control system applications. When replacing a modem, ensure the ST-connectors are cleaned with lint-free wipes and isopropyl alcohol to prevent signal loss due to dust contamination.
