MTL Redundant Fieldbus Power Supplies MTL 9189 is 8 segment N+1 redundant fieldbus power supply.
The 9189 fieldbus power system is designed to provide redundant power for eight, or four, Foundation™ fieldbus H1 segments for use with all fieldbus systems. It is optimised for use in general purpose and hazardous area High Energy Trunk architectures which, with the appropriate FieldPlus wiring components, supports fieldbus devices using all hazardous area protection techniques. The power supply has been designed to optimise cabinet layouts, maximising the number of fieldbus segments powered per cabinet while providing space for installing and maintaining cable connections and minimising the operating temperature.
SURGE PROTECTION
The design of the 9189 has made the installation of effective surge protection on fieldbus trunk a simple matter, through the
use of individual FS32 modules. A grounding bar is available, that is attached to the power supply carrier to provide both
mechanical support for the FS32 modules as well as a way of connecting them to a local low impedance ground point to
dissipate any induced surge currents. See the Accessories section below. A full technical datasheet for the FS32 is available
from the MTL website.
