F880

8-segment redundant fieldbus power system for use with Yokogawa CENTUM 3000 R3 Control System F880 ♦ Integrated redundant fieldbus power for ALF111 FOUNDATION fieldbus™ cards ♦ ♦ ♦ ♦ Low power dissipation Passive module carrier On-line diagnostics option Redundant power & conditioning ♦ ♦ High-density, compact design Fully isolated The F880 fieldbus power system is designed to provide redundant power for eight FOUNDATION fieldbusTM H1 segments when used with Yokogawa ALF111 fieldbus cards. The F880 module carrier has system connectors for direct connection to two redundant pairs of fieldbus cards using Yokogawa AKB336 cables. Power for the fieldbus segments is provided by two F801 power modules operating in a redundant configuration. Failure alarms, galvanic isolation, power conditioning and segment termination are incorporated into each F801 module. In simplex applications, a single F801 module may be used. Termination of the fieldbus segments is automatically maintained when single or redundant F801 modules are fitted. 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 F801 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. The alarm contacts are volt-free and galvanically isolated from other circuitry. Connections to the alarm relays are made via terminals on the F880-CA carrier. A separate alarm module is not required for this function. LED indicators also show the status of each F801 module and the eight individual segments. In normal operation, each segment LED is lit, showing that the segment is powered. If a segment is shorted, this LED is extinguished, and the module Alarm LED is lit. A separate physical layer diagnostics module may be installed on the carrier to automatically collect and distribute additional diagnostic information for each of the eight fieldbus segments. The F801 module provides galvanic isolation between the 24V DC input power and the fieldbus segments, as recommended by the IEC61158-2 fieldbus standard and the FIELDBUS Foundation™ FF-831 validation test for power conditioners.There is also galvanic isolation between the fieldbus segments, thereby preventing multiple segment failures due to ground faults on more than one segment. Each segment has its own fieldbus power conditioner and current limitation. Redundant 24V DC (nom.) input power is connected to the F880 carrier using two-part pluggable connectors. Field wiring connections are available with either pluggable screw terminals (F880PS) or pluggable spring clamp terminals (F880-PC).
