1 General Inroducion In measuremen, posiioning and conrol applicaions, i is necessary o monior and indicae he saus of he machine or insallaion. In order for he signal o be processed by he programmable conroller, i mus be presened in digial form or convered o one of he sandard signals of 0 20 ma, 4 20 ma or O 1O V. Murrelekronik can supply a wide range of inelligen inerface modules wih he addiional benefi of opo-isolaion of inpus and oupus. These modules presen a number of pracical advanages o he user: A wide supply volage range of V DC Oupu analogue value, I A analogue signal Sensor D Digial signal PLC I/O Digial signal MAW Processor MDW D analogue signal Moorized valve A Posiioning device Shor-circui proeced solid sae or elecro-mechanical relay oupus Opo-isolaion LED saus indicaor Mouning on D-rail AD/DA Converer Modules In order for he analogue signals, for example, from sensors o be acceped and processed by he conroller, hey mus be convered ino digial form. Analogue Coupler Modules The analogue signals from sensors and oher such measuring devices are usually in one of he sandard signal formas of 0 20 ma, 4 20 ma or O 10 V. The Murrelekronik analogue coupler modules will accep one of hese signals and change i o give an oupu in any of he 3 forms. The addiional benefi is ha he inpus and oupus are also opo-isolaed. A common problem occurs when a volage signal mus be ransfered over a long disance. In order o minimize he possibiliy of an incorrec volage signal being received, i is common pracice o conver he volage ino a curren signal. Similarly, he digial oupu signals from he PLC mus someimes be convered ino analogue signals, e.g. o conrol posiioning devices. The programmable conrol uni works in binary as does he Murrelekronik module. The higher he number of bis, he finer he resoluion and he beer he conrol. The signals from he sensors are convered ino he correc form for he PLC, processed and presened o he oupu field devices simply and effecively. The digial-analogue module convers binary signals ino one of he sandard signals of O 20 ma, 4 20 ma, O 10 V, whereas he analogue-digial module does he reverse. I Inpu signal curren 0 20 ma Analogue coupler module MW I Digial informaion Digialized analogue size Incremen 0,666 V V Oupu signal volage 0 10 V Value Example: A 4 Bi converer 2 4 = 16 levels corresponding o 15 incremens. If level 0000 = 0 V and level 1111 = 10 V, each incremen will represen V per bi. Example: To conver one signal forma ino anoher wih elecrical isolaion

2 The frequency o analogue converer from Murrelekronik will conver he sinusoidal oupu from a achogeneraor, or he pulse rain from an encoder, ino an analogue value proporional o he RPM. The oupu will be one of he sandard forms of volage or curren 0 20 ma, 4 20 ma or O 10 V. The oupu is opo-isolaed from he inpu o avoid inerference. Example: Mehod of connecion Window Discriminaor: 1 and 2 mus be conneced in parallel Ref 1 defines he lower limi of he window Ref 2 defines he upper limi of he window OT 3 OT 2 OT 1 I Signal conversion Frequency in volage or curren OT 1 OT 2 OT 3 under operaing poin in window over operaing poin Ref. 2 Ref. 1 f, I Temperaure Converer Modules In indusry, mos emperaure measuremens are made wih a resisance ype hermomeer, where he probe is supplied wih a consan volage and he oupu varies wih he change in resisance caused by changes in he emperaure. The mos commonly used probe is he PT 100 ype. AD Converer MAW A D Value via PLC PLC I/O Connecing he probe o he Murrelekronik MTW module gives he probe he necessary volage supply and also convers is oupu o he sandard signal forms of 0 20 ma, 4 20 ma or 0 10 V. The errors due o he cable resisance can be compensaed for on he module. Example: To conver a pulse rain ino analogue volage and hen ino digial binary forma. Comparaor Modules The Murrelekronik comparaor modules compare o he analogue volage or curren values wih inernal or exernal references o overshoo and undershoo hese adjusable limis and give up he corresponding oupu signals. The desired se poin succeeds eiher above he locaed module poeniomeer or exernally above he erminal connecion.

For he direc inpu of sandard analogue signals in digial conrol sysems or he analogue conrol of equipmen via digial signals. Page MW, MIW, MIW, MIIW, MLTIWANDLER The analogue-coupler modules can make differing analogue signals, which occur in he sensor and oupu circuis (0 10 V, ± 10 V, 0 20 ma, 4 20 ma) work ogeher. The inpu and oupu circuis are galvannically separaed. Wih he new MLTIWANDLER all funcions can be covered only wih he module. From page RM Moor proecion relays o proec and monior moors wih inegraed emperaure sensor. The modules have 2 conacs. Page MFW, MIFW Over long disances, signals can be falsified or damaged due o he cable resisance and oher inerference. This can be sopped by convering he sandard oupu signals ino an equivalen frequency signal. Signal inpu and oupu are elecrically isolaed. Page MFW, MFIW The frequency converer convers frequency signals up o 100 khz ino an equivalen analogue signal (0 10 V, 0 20 ma, 4 20 ma). Herewih, i is possible o process impulse signal chains from i.e. revoluion or speed measuremens from conrollers which do no have he abiliy o accep rapid number inpus. Page MIB The pulse exension modules increase he lengh of very shor impulses which canno be used as a defined conrol signal o he conroller. Conrol signals wih a lenghened cycle ime can hen be acceped and processed by slower PLC sysems. MAK The comparaor modules are designed o monior and regulae simple auomaic processes. Two possible applicaions can be covered: 1. Monioring an analogue inpu signal o see if i goes ouside pre-defined limis 2. Monioring an analogue inpu signal o see if i remains wihin pre-defined limis Page Page

4 MTW Signals from a PT 100 Sensor are convered using he emperaure converer modules ino sandard oupu signals (0 10 V, 0 20 ma, 4 20 ma). I is herefore easy o make a cos-effecive connecion beween he process monioring and he process adminisraion (i.e. PLC). To sop signal corrupion which occurs due o cable resisance, he module allows for 3-wire measuremen compensaion. Page MESCO Measuring and monioring relays o monior and measure elecrical values. They boh conrol and safeguard sysems. MESCO modules are used in AC, DC and hree phase applicaions where exac volages, emperaures, levels and roaional speeds need o be measured. The erminal block are removable which reduces servicing ime. Double chamber erminals allow 2 wires of differing diameers o be conneced. From page
