Precision, AC Current to Voltage Transducer
The CR4310 series
current-to-voltage transducer produces a 0-5 Vdc output signal that is directly
proportional to the input AC current. The output signal is average-sensing, calibrated for
RMS.
This transducer is used with process control and industrial instrumentation equipment. The DC output signal can be connected directly to a high impedance analog input of a computer or PLC without additional signal conditioning.
The CR4310 series will measure up to 200% of full scale on a short time basis (1 minute or less) and 150% on a continuous basis at its rated accuracy.
To protect external circuits from damage caused by short circuits or motor inrush currents, the output is limited to 12 Vdc.
