1、GeneralGood power supply managementis at the heart of the MTL8000system.AC and DC power supply units areavailable to suit the availableresources.All units are designed to endurethe harsh environmentalconditions that are frequentlyfound in process plants and,naturally,they meet rigorous EMCand electr

2、ical safety standards.Power supply connections areminimised and simplified toensure that power provisionrequires the minimum of wiringeffort 8000 series power supplies aredesigned to support redundancywhen required.Most have“health”signal outputs for earlywarning of problems.EUROPE(EMEA)Tel:+44(0)15

4、range of 18.5 up to36V.This input voltage range accommodates the typical 24 V DC suppliesavailable on process plants worldwide.This power supply is designed to mountdirectly on 8711-CA-NS or 8712-CA-NSnode services carriers or on a 8717-CA-PSpower supply carrier.On the node servicescarriers mentione

5、d here,two positions areprovided.This enables a second powersupply to be mounted,under conditionswhere the user wants to provide additionalpower,or where a redundant power supplyis required to provide maximum systemavailability.DC IS module supplyPower Supply module 8920-PS-DC mountson its own carri

6、er(8724-CA-PS)and acceptsa locally available 24V dc(nominal)supply and converts it to 12V dcfor powering MTL8000 I/O modules thathave intrinsically safe field wiring.Its 5A output is capable of poweringbetween six and twenty I/O modules,depending on the module types and theirmix.A number of 8920-PS-

7、DC modules may beused together,within an MTL8000 node,ina load-sharing arrangement.Where powersupply redundancy is required an additional supply module may be added inan“n+1”arrangement.Failure of anypower supply is signalled to the Bus InterfaceModule.AC power suppliesThe 8913-PS-AC and 8914-PS-AC

8、suppliesproduce DC output power from a widerange of AC inputs.Both can be mounted ina Zone 2 or Division2 hazardous areawhich means that they can be used for abroad range of applications includingsupplying power to 8000 series modules.System powerThe 8913-PS-AC is a dual output supplycapable of prod

9、ucing 12 V and 24 V DCoutputs of approximately 5 A.For 8000 series products,the 12 V outputcan be used to supply system power to thenode and also provide 24 V to power fielddevices via the field power bussing facilitieson the 8000 series carriers.Field powerThe 8914-PS-AC has a single 24 V DCoutput

10、with a 10 A capacity.This is ideal forpowering a wide range of field devices.With 8000 series products,it is normallydistributed via the field power bus(seebelow).Load sharingA load sharing diode is built in to the 12Voutput of the 8913-PS-AC power supply andthe 24V output of the 8914-PS-AC.Thisenab

11、les one or more of the same powersupply type to be connected in parallel toshare the load requirements.Power health signallingThe 8913-PS-AC and the 8914-PS-ACsupplies provide power health signals thatcan be routed to the BIM to warn of possibleimminent power failure.The 8913 provides the power heal

12、th signalfrom its 12 V DC output.Bussed field power (2/2 modules/carriers only)In addition to the system power supply,anMTL8000 node may need to be suppliedwith additional field power.Conventional systems require field powersupplies to be wired in at the field terminalsor via additional patching con

13、nectors.Thisadds complication to the field wiring andcan be a source of confusion during maintenance work.The MTL8000 system overcomes this complication with a system for bussingpower on the carriers.Each carrier can busan external power supply to modules so thatthey can energise the field wiring.In

14、 the case of the 4-20mA Analog Input andOutput modules,the bussed field power isalso used to energise the field interface circuits.The connection for the bussed field power islocated at the top of the carrier and uses atwo-part removable connector.Individualbussed field power supplies connect to two

15、modules.If an adjacent pair of modulesrequire the same power supply voltage theconnector can be wire-linked to provide it,otherwise a different supply voltage(AC orDC)can be connected.EUROPE(EMEA)Tel:+44(0)1582 723633 Fax:+44(0)1582 422283AMERICASTel:+1 603 926 0090Fax:+1 603 926 1899ASIA PACIFICTel
