ABB TB840A Modulebus Cluster Modem In Stock

Overview

The ABB TB840A is a fiber optic interface for the ModuleBus communication network. It enables reliable data transmission over long distances using fiber optic cables, improving noise immunity compared to electrical connections.


Features

• Fiber Optic Connectivity: Connects to the ModuleBus network via fiber optic cables.
• Increased Distance: Extends communication range beyond the limitations of electrical connections.
• Redundancy Support: Enables redundant configurations for enhanced system reliability. In this scenario, each TB840A connects to separate optical ModuleBus lines while remaining connected to the same electrical ModuleBus.
• CE Marking: Complies with relevant European safety and electromagnetic compatibility directives.

Technical Specifications

• Reliable Long-Distance Communication: Ideal for industrial automation applications where equipment is spread across large distances.
• Improved Noise Immunity: Fiber optic cables are less susceptible to electrical noise interference compared to traditional copper cables, ensuring data integrity.
• Enhanced System Reliability: Redundancy configurations with the TB840A minimize downtime risks in case of a single fiber optic line failure.
