Precision, AC Current to Voltage Transducer
The
CR431
series, Current-to-Voltage Transducer produces a 0-5 Vdc or 0-10 Vdc output signal that is directly proportional to the input AC current. The out- put 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 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.
