EMBSIN 100 I Transducer for AC current - Mbs-ag.com

EMBSIN 100 ITransducer for AC currentSelf-poweredWith 2 measuring rangesCarrying rail housing MBS/SP1ApplicationThe transducer EMBSIN 100 I (Fig. 1) converts a sinusoidal ACcurrent signal into an output signal that can serves several receivinginstruments such as indicators, recorders, alarm units etc.The transducer fulfi ls all the important requirements and regulationsconcerning electromagnetic compatibility EMC and Safety (IEC1010 resp. EN 61 010). It was developed and is manufactured andtested in strict accordance with the quality assurance standardISO 9001.Fig. 1. EMBSIN 100 I transducer in housing MBS/SP1clipped onto a top-hat rail.Features / Benefits● Measuring input: 2 measuring ranges, 1/5 A or 1.2/6 A● Self-powered / Less wiring expense● Low power consumption / Smaller CT’s can be used● Alternatively as marine version per Lloyd's Register of ShippingLayout and mode of operationThe transducer comprises a transformer W, a rectifi er unit G andan amplifi er V (Fig. 2).The measured variable is isolated from the electronics by thetransformer, and is rectifi ed and smoothed in the rectifi er unit.The amplifi er amplifi es the resultant signal and converts it into theload-independent DC signal.Table 1: Base versionsThe following transducer versions are available as base versions.It is only necessary to quote the Order No.:DescriptionTransducer for ACcurrent,nominal frequency50 / 60 Hzin housingMBS/SP1Measuringrange, selectableat terminalsOutputsignalOrder No.0…1 A / 5 A 0… 5 mA 127 6980…1 A / 5 A 0…10 mA 127 7050…1 A / 5 A 0…20 mA 127 7130…1.2 A / 6 A 0… 5 mA 127 7210…1.2 A / 6 A 0…10 mA 127 7390…1.2 A / 6 A 0…20 mA 127 747Please complete the Order Code 100 I-M... . acc. to “Table 2:Specifi cation and ordering information” for versions with userspecific input ranges and/or variable sensitivity.E135/6 A~1/1.2 A~2W G V–5 –6 +ATechnical dataMeasuring input ENominal frequency:Fig. 2.
