ModuleBus Modem I/O Extension | ABB TB820V2 3BSE013202R1

Product Description

The TB820V2 (Part Number: 3BSE013202R1) is a high-performance ModuleBus Modem engineered for the ABB S800 I/O system. While often broadly categorized alongside temperature transmitters in simplified catalogs, the TB820V2 serves a critical infrastructural role as an optical-to-electrical signal converter. It enables the extension of the ModuleBus over fiber optic links, connecting a central AC 800M controller to remote S800 I/O clusters while ensuring complete galvanic isolation.

As the advanced successor to the original TB820, the TB820V2 offers enhanced stability and signal integrity for distributed process control. By utilizing fiber optics, it effectively eliminates ground loop problems and provides immunity against electromagnetic interference, which is vital in heavy industrial environments like power plants or refineries. The module is designed for 24 VDC operation and features a compact, rugged form factor for DIN rail mounting inside marshalling cabinets.
