segment is automatically maintained when single or redundant Power Modules are 
fitted.  The F890-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 F890-CA carrier using two-part pluggable connectors.  
Field wiring connections are available with either pluggable screw terminals (F890-PS) 
or pluggable spring clamp terminals (F890-PC).
