1 OVERVIEW
The F101, F102, and F104 (F10x) Fieldbus Power Supplies are designed to provide power
for a single FOUNDATION fieldbus™ H1 or Profibus PA segment. Galvanic isolation, power
conditioning and segment termination are incorporated into each F10x module. Termination
of the fieldbus segments is normally enabled with a switch on the module, but may be
switched off for those few applications that do not require a Terminator at the Fieldbus Power
Supply.
2 DESCRIPTION
For extreme reliability, the modules use passive components for power conditioning and a
reliable DC/DC converter to provide galvanic isolation and power regulation. The connectors
used for power input and the Fieldbus output are high quality pluggable types with screw
retention. Spring-clamp (-PC) and screw terminal (-PS) connector versions are supported.
LED indicators show the status of the modules. In normal operation, the green Power LED
is lit, showing that there is proper input voltage to the module and the red Fault LED is off.
If the fieldbus segment is shorted or in an over-current condition the Fault LED blinks. An
internal module error is indicated by a steady light on the red Fault LED. The status of the
internal terminator switch is also indicated by an illuminated 'T' symbol.
The modules can be powered from a supply between 19.2 – 30.0 VDC (10.0 – 30.0 VDC
for the F104). The incoming power can be applied via the top-mounted connector which
supports onward looping of power wiring, or by using a proprietary plug-in connector on a
DIN-rail bussing system.
