technical datasheettechnical datasheetF650Aredundant <strong>power</strong> system for use with Honeywell Experion PKS FIM• Integrated redundant fieldbus <strong>power</strong>system for Honeywell control systems• Replace <strong>power</strong> modules withoutinterrupting the fieldbus• High <strong>power</strong> output• Two levels of <strong>power</strong> redundancy• Component failure alarm• Integrated fieldbus terminatorsThe F650A is designed to provide redundantfieldbus <strong>power</strong> conditioners for theHoneywell Experion PKS Fieldbus InterfaceModule (FIM), supporting two H1 fieldbussegments. Each F650A includes two FPS-IPMplug-in <strong>power</strong> modules for each of the fieldbussegments. These modules function as <strong>power</strong>conditioners, providing impedance betweenthe input DC <strong>power</strong> supply and the fieldbus.This impedance is necessary to prevent theinput DC <strong>power</strong> supply from degrading thedigital fieldbus signal. One fieldbus segmentterminator is permanently connected in eachsegment.A separate alarm module monitors thestate of each of the four <strong>power</strong> conditioningmodules and the redundant <strong>power</strong> inputs. If afault is detected on any of these components,a red alarm LED provides visual indication ofthe fault and an alarm signal is sent to theHoneywell control system via the multi-wayconnnectors. This allows failed components tobe replaced so that <strong>power</strong> system integrity ismaintained. The alarm circuitry is galvanicallyisolated from the fieldbus segments and input<strong>power</strong> supplies. Green LEDs on each <strong>power</strong>module and two input <strong>power</strong> supply LEDs onthe alarm module give clear visual indicationthat components are functioning properly.The F650A has the same dimensions asa size A Honeywell Remote TerminationPanel (RTP), and is suitable for the standardmounting channel. Alternatively, the panelmay be mounted on DIN rail using the DMK-HONA mounting plate, available from MTL.The F650A provides connections toredundant Honeywell Experion PKS FIM’susing standard Remote Termination Panelcables from Honeywell (type TC-FFC0XX).Field connections are via pluggable screwterminal connectors. For redundant operation,two separate DC <strong>power</strong> supplies should beconnected to each F650A. A separate terminalis also provided to connect the fieldbus andhost cable screens to a common point, suchas the local cabinet ground.EPS-F650A Rev1 090410www.mtl-inst.comenquiry@mtl-inst.com
