2 68 kg)The CR4320series, loop-powered, 2-Wire CurrentTransmitter produces a calibrated 4-20 mA. DC Output Current directly proportional to the averageRMS value of the input alternating Current . The controlled Current Output is unaffected by variations in supply voltage, interconnect and load impedance(within specification limits) to provide a highly accu-rate means for monitoring alternating Current overlong NumbersCR4320 - qqq4-20 MA Current TRANSMITTERFull-Scale (FS)Range in AC AmpsCaseStyle Case Style 1 Case Style 2 E154235 Internet Resources Selection Guide: Sheet: : Loads: Magnetics, Inc. 544 Axminister Dr. Fenton MO USA 63026 V: F: : : Notes2- wire Current Transmitter4-20 mA ( ) ( ) ( ) ( ).50 ( ) (60) ( ).25 ( )# 10-32(Use M4 terminals).93 ( ) ( ).

LOOP Current OUTVSFULL-SCALE INPUT CURRENTCase Style 1 Case Style 2 Typical ApplicationsAn external Current transformer may be used with the transmitter by routing the secondary leads through the window opening. Use the CR4320-5 Current transmitter when using a 5 Amp secondary instrument grade Current transformer. For additional details on Current transformers, see page scaling factor may be changed by threading the primary Current -carrying wire several times through the window opening. The "actual" measurement range will be the name plate range divided by the number of wire passes. For example, the CR4320-30 has the name plate range of 0-30 Aac. Two passes of the wire through the window opening will then provide an effective range of 0-15 Aac (30 2).
