Power Supply

It is recommended to feed the system components and field equipment from

different power supplies. Example of system components are Controllers,

Communication Modules, Fieldbus Communication Interfaces and Modulebus

Modems, (for instance PM864A, CI854A, CI840A and TB840A). Example of field

equipment is transmitters, actuator as well as the field side of the S800 I/O modules

(terminals on MTU and S800L marked L+ and L-).

The power supplies can also be configured in a redundant configuration using

independent voting units.
