1. General Introduction
TB842 Module Bus Optical Port is a communication interface between the CI801 or CI840/CI840A FCI and the TB820/TB820V2/TB840/TB840A Module Bus Modem of an I/O cluster or ABB drives units via the Optical Module Bus. TB842 connects to CI801 via TB806 and to CI840/CI840A via TU847 and TB806 for single I/O or via TU846 and TB846 for redundant I/O.
TB842 can be used in both a simplex optical configuration as well as in a duplex optical configuration. In a simplex configuration, the optical Module Bus nodes are connected in a ring. In a duplex configuration, the optical Module Bus nodes are connected in a row. TB842 has a connector for fiber optic connections and a connection to the communication interface module.
The module is equipped with Transmitter/Receiver for up to 10 Mbit/s. Both plastic and HCS (Hard Clad Silica) optic fiber with connectors (Agilent’s, former Hewlett-Packard, and Versatile Link) can be used with the TB842.
