1 Curren ransducer up o 55 A, programmable and configurable Daa shee _en_11 PHOENIX CONTACT Descripion The MCR-S-...-DCI curren ransducers offer users he opion of ordering a preconfigured device, configuring he device hemselves via DIP swiches or programming i wih MCR/PI-CONF-WIN configuraion sofware (Order No ). Power FL IN I POWER The MCR-S-1-5-UI-DCI module provides no only he sandard 1 A and 5 A inpu signals, bu also he opion of seing curren ranges of A o A progressively. Wih a measuring range of A o A, he MCR-S UI-DCI is ideal for measuring higher moor currens. U,I DC, AC, and disored currens can be equally well measured. In addiion o an analog oupu, hese curren ransducers also have an opional relay and ransisor oupu, e.g., for alarm monioring. When ordering, he desired configuraion o which he device is o be adaped mus be specified (see order key on page 6 and page 9). Feaures Progressive adjusmen of measuring range True r.m.s. value measuremen 3-way elecrical isolaion according o EN Wih opional relay and ransisor oupu 22.5 mm ME housing Observe he safey noes on page 11.

11 6 Insallaion and sarup 6.1 Safey noes During operaion, cerain pars of his elecric measuring ransducer may carry hazardous volages. Disregarding his warning may resul in serious personal injury or damage o propery. MCR-S-...-DCI Modules mus only be insalled and sared by qualified personnel. Qualified personnel are people who, because of heir educaion, experience and insrucion and heir knowledge of relevan sandards, regulaions, acciden prevenion and service condiions, have been auhorized by hose responsible for he safey of he plan, o carry ou any required operaions and who are able o recognize and avoid any possible dangers. The ransducer mus no be sared up when he housing is open. The poeniomeers on he fron should only be adjused using a screwdriver, which is safely isolaed from he volage a he inpu. For applicaions wih high operaing volages, ensure sufficien disance or insulaion and provide shock proecion. Safe and error-free operaion of his device can only be ensured if ranspor, sorage, and assembly are carried ou correcly and operaion and mainenance are carried ou wih care. 6.2 Mehod of operaion Connecion o he inpu erminal blocks (MCR-S DCI) or passing he live conducor hrough he curren ransducer (MCR-S DCI) induces a magneic flux in he sripwound core. The magneic flux densiy is measured using a Hall sensor and convered proporionally from he inpu curren o a volage (Hall volage). A subsequen rue r.m.s. value converer enables DC, AC, and disored currens o be measured. The signal is amplified for furher processing and made available as a proporional analog signal a he oupu. 6.3 Elecrical connecion Pin assignmen When operaing his elecric measuring ransducer, he naional regulaions (e.g., in Germany, VDE 0100 "Condiions for he Erecion of Elecrical Power Insallaions wih Nominal Volages Below 1000 V") mus be observed during he insallaion and selecion of he elecrical conducors.

The configuraion daa for a preconfigured device can be found on he righ hand side of he housing. If you are using an unconfigured ransducer, here is a sandard configuraion which can be found in he order keys on page 6 and page 9. If he desired configuraion does no mach he label on he side of he housing or he sandard configuraion, refer o he secion below. 6.5 Configuraion flowchar Configuraion or programming Opening he housing Configuraion of he inpu curren range and measuring process Configuraion of he analog oupu Programming Configuraion via DIP swiches Sofware package Configuraion or programming The MCR-S-...-DCI generaion offers he advanage of a choice beween configuraion and programming. MCR/PI-CONF-WIN sofware can be used o freely program he rue r.m.s. value curren ransducer. Programming is explained in he sofware manual. The user-friendly configuraion sofware runs under all popular Windows operaing sysems. In addiion o programming, modules can be parameerized using DIP swiches and poeniomeers. The res of his secion deals wih configuraion: Opening he housing The ransducer mus no be sared up when he housing is open.

This seady-sae value generaes he same hermal work in an ohmic resisor as a DC curren of idenical magniude. The erm "rue r.m.s. value" simply indicaes ha disored and pulsaing currens are also measured. Arihmeic average value: The arihmeic average value is used o measure DC currens or o filer a DC porion from a pulsaing curren. Using he arihmeic average value on a symmerical AC curren would resul in he measured value being "0". The arihmeic average value can be used o make bipolar DC currens available as analog sandard signals a he oupu. 1 Only for MCR-S-...--DCI Seing DIP swich 10 o configuraion mode (DIP swich 10 o "OFF") swiches all poeniomeers o "acive".

This cable has a sereo jack connecor on one end for connecion o he curren ransducer and a 25-pos. D-SUB female connecor on he oher end for connecion o a compuer. For connecion o he compuer, an adaper cable for he inerface converer is usually required (9-pos. D-SUB female connecor o 25-pos. D-SUB male connecor, Order No ) _en_11 PHOENIX CONTACT 18

The MCR curren ransducer can ransfer corresponding sandard signals abou he moor load o he conrol sysem or service personnel. The rue r.m.s. value measuremen process means ha AC, DC, and disored currens can be measured.
