Eaton Crouse-Hinds F892 Instruction Manual

2INM F892 Rev 1current limitation and passive fieldbus power conditioner. Termination of the fieldbussegment is automatically maintained when single or redundant Power Modules arefitted. The F892-CA carrier is equipped with connectors that will accept an F809Fdiagnostic module. The module continuously monitors the performance of each of theeight fieldbus segments, providing information on the network health.Each Power Module has indicator LEDs to show both its status and that of the eightsegments under power. In normal operation, each green ‘Segment’ LED is lit, showingthat the segment is powered. If a segment is shorted, or its voltage is below the ratedoutput, 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. Earlyversions of the F892 only included one set of connectors (unit date code 0711 andearlier) and thus did not support redundant Host connection.3 COMPONENTS AND ACCESSORIESF801 8 Segment Power Module: 21 5V, 350mAF802 8 Segment Power Module: 28V, 500mAF809F 8 Segment Fieldbus Diagnostic ModuleF892-CA-P* CarrierF892-P* F892-CA-P* and two F801 modulesF892-2-P* F892-CA-P* and two F802 modulesF892-P*-NR F892-CA-P* and one F801 moduleF892-2-P*-NR F892-CA-P* and one F802 moduleF800-BLK Blanking Module included with –NR systems* = S – Pluggable Screw Terminal ConnectorsC – Pluggable Spring Clamp Connectors
