Current transducers are electrical devices that measure the level of electric current in a circuit and output an electrical signal proportional to the measured current. The CR4220-10 is a current transducer made by Sencon Instruments and is commonly used in industrial control, monitoring and measurement applications.

The CR4220-10 is encapsulated in a die-cast aluminum housing for protection against environmental factors and is designed to have an IP66 rating. It is rated for currents up to 10A, and it has an accuracy of +/- 1%. It is designed for easy installation, with mounting feet that fit in standard panel-mounted receptacles and an open-frame construction that allows for fast and easy toroid mounting. The transducer is also designed for operational flexibility with a wide operating temperature range of -25°C to 70°C.

The CR4220-10 operates using a low-cost, transformer-based current-sensing technique. The transformer primary winding is connected in series with the line that is being monitored. The current flowing through the transformer creates a magnetic field, and this field is sensed by a secondary winding in the transformer. The signal created by the secondary winding is then amplified and filtered by an integrator and interpreted by the circuitry in the device.

The output of the transducer is a proportional analog current signal. This signal is the result of the current through the line being multiplied by a predetermined gain factor. The gain factor is chosen according to the application, and the output current is inversely proportional to the system load. The output signal can be used to control other circuits or to measure the current being monitored.

The CR4220-10 is a simple and effective device for monitoring and controlling electrical currents, and it is commonly used in industrial systems for maximum reliability and accuracy. With its low-cost and easy installation, the CR4220-10 can provide a cost-effective solution for many applications.
