CR Magnetics CR4220S-150 AC Current Transducer

The CR Magnetics CR4220S-150 is a loop-powered AC current transducer that converts the current flowing through an AC conductor into a standardized 4-20 mA output signal, enabling direct connection to conventional current-loop instrumentation and control equipment without a separate power supply. It specifies an input range of 0-150 A AC, with the -150 suffix indicating this particular model variant within the CR4220S family, and it provides a proportional current output that reflects the sensed AC current. Manufactured by CR Magnetics, this transducer serves as a straightforward, inline means of monitoring AC current and feeding a reliable current-loop signal to measurement devices and process instrumentation that accept 4-20 mA inputs.
