FOUNDATION Power Supply/Conditioner
More Information:
The F8xx fieldbus power system is designed to provide redundant power for
eight FOUNDATION fieldbusTM H1 segments. Versions are available for
direct integration into all major DCS. Power for the fieldbus segments is
provided by two F802 power modules operating in redundant configuration
(load sharing). Failure alarms, galvanic isolation, power conditioning
and segment termination are incorporated into each F802 module. In
simplex applications, a single F802 module may be used. Termination of
the fieldbus segments is automatically maintained when single or
redundant F802 modules are fitted. Each segment has a nominal output
rating of 28.0V, 500mA, and is capable of powering heavily loaded
networks and long trunk cables.
For extreme reliability, the module carrier has no components and only
provides interconnections between the power modules and external
connections. It is supported in a rigid metal frame that protects the
circuit board from mechanical damage. Secure DIN rail mounting is
provided by integrated fixings.
Each F802 module monitors the output of the eight fieldbus segments and
indicates an alarm by means of a built-in, normally closed relay if any
of the segments is shorted, or below the minimum output voltage
threshold. Failure of either of the bulk power input supplies is also
annunciated.
