<strong>CR4311</strong> <strong>AC</strong> <strong>Current</strong>-<strong>to</strong>-<strong>Voltage</strong><strong>Transducer</strong>, 0-<strong>10Vdc</strong> outputThe CR431 series, <strong>Current</strong>-<strong>to</strong>-<strong>Voltage</strong> <strong>Transducer</strong>produces a 0-5 Vdc or 0-10 Vdc output signal that isdirectly proportional <strong>to</strong> the input <strong>AC</strong> current. The outputsignal is average-sensing, calibrated for RMS.This transducer is used with process control andindustrial instrumentation equipment. The DC outputsignal can be connected directly <strong>to</strong> a high impedanceanalog input of a computer or PLC without additionalsignal conditioning.The series will measure up <strong>to</strong> 200% of full scale on ashort time basis (1 minute or less) and 150% on acontinuous basis at its rated accuracy.To protect external circuits from damage caused byshort circuits or mo<strong>to</strong>r inrush currents.•••••FeaturesPermanently calibrated<strong>Output</strong> overload protectedFully isolated10 different rangesSelf-powered, requires no externalpower sourceSpecificationsAccuracy:Depends on the range and load resistance, seePart Numbers tableRipple:1% Max. peak ripple on outputCalibrated Signal Out:0-5 Vdc for CR43100-10 Vdc for <strong>CR4311</strong>Response Time:250 ms max., 10-90% FSMax.

Use theCR4310-5 or <strong>CR4311</strong>-5 current transducer with a 5 Amp secondaryinstrument grade current transformer. For additional details on currenttransformers, see page 25.3-PHASE SYSTEMSThree-phase systems may be moni<strong>to</strong>red by attaching three transducersin series. The <strong>to</strong>tal output voltage will be the sum of each individualtransducer. If each transducer is sized for the full-scale current, theoutput voltage will be 0-15 Vdc for the CR4310 Series (0-30 Vdc for the<strong>CR4311</strong> Series) at 0 <strong>to</strong> 100% full-scale. As an alternate, each transducermay be sized for three times the full-scale current, then the outputvoltage for the CR4310 will be 0-5 Vdc for 0 <strong>to</strong> 100% full-scale.Web: http://www.jimdgrayassoc.comEmail: jimgray@jimdgrayassoc.com
