The unique design of the CR4210 Transducer allows the system designer to not only measure individual phase cur-

rents, but also combine signals to realize arithmetic functions with a minimum of components and programming.

Because of the self-powered floating output feature, voltages can be added and subtracted by simple wiring, and

accurate data displayed via programmable scale displays.

Accurate average three phase current measurement

Phase imbalance indication Monitor motor load status accurately and simply

Monitor heater status and balance

Phase Voltage monitor

The transducer function of giving DC output voltages for AC input currents loses all phasing information.

Absolute values of current are available only.

Loading limits of the transducer remain as specified. Multiple transducers wired as shown must be capable of

handling the instrument impedance on an individual basis.

Transducers may be mounted in close proximity to each other without concern for magnetic interaction.

An external current transformer may be attached to the transducer for applications that require monitoring

current levels above 200 AAC.
