Detailed data
ABB TB840A 3BSE037760R1 ModuleBus Modem
S800 I/O is a comprehensive, distributed and modular process I/O system that communicates with parent controllers and PLCs over industry-standard field buses. The TB840 ModuleBus Modem is a fiber optic interface to the Optical ModuleBus. TB840A is used in redundancy configurations where each module is connected to different optical ModuleBus lines, but connected to the same electrical ModuleBus.
The ModuleBus Modem has an electrical and an optical Modulebus interface which are logically the same bus. A maximum of 12 I/O modules can be connected to the electrical ModuleBus and up to seven clusters can be connected to the fiber optic ModuleBus. The fiber optic interface is intended for local distribution of I/O clusters and where more than 12 I/O modules are required in an I/O station.
The TB840A is designed for long-distance communications. It allows data to be transmitted over long distances, ensuring devices can be effectively networked even when they are physically far apart. It supports communications over twisted pair or fiber optic cables, making it a flexible choice for installations that require long distances or higher bandwidth.
Frequently asked questions about the product are as follows:
-What is the function of the ABB TB840A 3BSE037760R1 ModuleBus modem?
The TB840A ModuleBus modem supports long-distance communication between ABB control systems and field devices using ModuleBus. It converts signals between RS-232, RS-485, and ModuleBus, facilitating reliable data transmission over long distances in industrial environments.
-What is the maximum communication distance supported by the TB840A modem?
The TB840A modem can support communication distances of up to 1,200 meters or more, depending on the type of communication line and specific environmental conditions.
-Can the TB840A modem be used with non-ABB systems?
The TB840A modem is primarily intended for use with ABB systems, especially ModuleBus networks. However, it may be possible to use it with other systems that support compatible communication protocols. Compatibility depends on the specifics of the communication standard of the non-ABB system.
