The TB846 redundant ModuleBus Cable Adaptor is used together with TB845 and two TK801V0xx to extend the ModuleBus. Using this extension I/O modules on the same electrical ModuleBus can be mounted on different DIN rails. TB846 can also be used together with TB842 to provide an optical extension of the ModuleBus.
ABB has been concerned with environmental issues for a long time. Consequently, the ABB group was an early adopter of ISO 14001-based environmental management systems and has formally been certified to that standard for years.
An important component of those systems is Life-cycle Assessments (LCA’s) of the ABB group’s products. These involve studying the environmental impact of products over their lifetimes by quantifying the input of energy and raw materials needed and the emissions and waste generated throughout the products’ lifecycles. These studies are carried out according to the ISO 14040-43 standard and then condensed into environmental declarations like this one.
Consequently, the environmental management systems specify how the group’s environmental work shall be carried out while the environmental declarations describe the results of that work.
The Product Covered by this Declaration
This environmental declaration covers a range of
input/output modules for industrial process control, designated by ABB as S800 I/O (Figure 1),
consisting of plastic cases, containing printed
circuit boards, connectors, electrical conductors
and fasteners. The modules are made for fitting
onto metallic mounting rails.
The weight of each module is approximately 0.5 kg
(1.1 lbs) and the distribution across constituent
materials is illustrated by diagram 1.
