current limitation and passive fieldbus power conditioner. Termination of the fieldbus
segment is automatically maintained when single or redundant Power Modules are
fitted. The F892-CA carrier is equipped with connectors that will accept an F809F
diagnostic module. The module continuously monitors the performance of each of the
eight fieldbus segments, providing information on the network health.
Each Power Module has indicator LEDs to show both its status and that of the eight
segments under power. In normal operation, each green 'Segment' LED is lit, showing
that the segment is powered. If a segment is shorted, or its voltage is below the rated
output, its LED is extinguished, and the red 'Alarm' LED is lit. Redundant 24V DC (nom.)
input power is connected to the F892-CA carrier using two-part pluggable connectors.
Field wiring connections are available with either pluggable screw terminals (F892-PS)
or pluggable spring clamp terminals (F892-PC).
The figure below shows two sets of 8 connectors for connection to the Host. Early
versions of the F892 only included one set of connectors (unit date code 0711 and
earlier) and thus did not support redundant Host connection.
