ABB TC514V2 3BSE013281R1 Twisted Pair To Optical Repeater

Product Overview

The ABB TC514V2 (3BSE013281R1) is an industrial-grade signal repeater designed to convert and extend twisted pair electrical signals to optical fiber signals and vice versa. It is typically used in distributed control systems (DCS) or PLC networks to isolate, protect, and extend communication lines.

This unit plays a vital role in environments where electromagnetic interference (EMI) is present or where long-distance communication is required. By converting electrical signals into optical ones, it ensures data integrity, signal reliability, and network stability across harsh industrial environments.

As part of ABB’s control system accessory portfolio, the TC514V2 is optimized for integration with ABB’s Advant Master, 800xA, and other industrial automation systems.
