ABB S800 ModuleBus Interface Characteristics
The TB806 operates as a passive ModuleBus interface adapter within ABB S800 I/O configurations. Therefore, it supports physical connection extension between compatible ModuleBus components while maintaining the electrical characteristics of the communication path.
In addition, ABB S800 architecture depends on defined backplane and ModuleBus communication structures. The TB806 provides the required connector conversion function without adding firmware processing or active communication control.
Furthermore, the adaptor supports industrial installation requirements with specified hazardous location approvals and environmental protection classifications. The unit maintains compatibility with ABB ModuleBus extension arrangements where D-SUB 25 male interfaces are required.
