TB820V2 3BSE013208R1 ABB Modulebus NEW

TB820V2 (3BSE013208R1) is a Modulebus optical cluster modem belonging to ABB S800 I/O system. It serves as the communication interface for Modulebus, used for non-redundant optical connection between the controller and S800 remote I/O clusters. It converts electrical Modulebus signals into optical signals to extend communication distance and enhance anti-interference capability. It is widely deployed in ABB System 800xA and Freelance DCS systems for petrochemical, power, pulp & paper and other process industries. It comes with power supply connector and TB807 Modulebus terminator as standard accessories.
