This CR Magnetics CR5210 series current transducer combines a solid-core current transformer and signal conditioner, and is suitable for use in industrial automation systems. The transducer provides magnetic modulator measurement for direct currents, with an accuracy of 1.0% full scale (FS) and a response time of 250 ms (10-90% step change). Mounting options include DIN rail or panel. This current transducer is Restriction of Hazardous Substances (RoHS) compliant for environmental protection. It is suitable for monitoring direct current (DC) loads.

Current transducers are used to detect electrical current flowing in a wire or cable, and to generate an electrical signal proportional to the current for measurement or control. The transducer consists of an electrical winding, a magnetic core, and a signal conditioner. When current flows through a wire, the transducer winding generates a current, which produces a magnetic field in the core, which then creates a proportional current or voltage output signal. Current transducers are used in industrial automation systems for monitoring, alarming, and equipment control.
CR Magnetics manufactures electrical sensors, indicators, and displays. The company, founded in 2004, is headquartered in Saint Louis, MO.
