The CR4820-250 is a monitor-current/voltage transducer that is used in a variety of applications to measure current and voltage levels. The device is designed to measure two-wire currents that are in the range of 0.2-25A and two-wire voltages of 18-250V AC/DC. The CR4820-250 is suitable for applications such as motor control, power monitoring, and lighting control.

The CR4820-250 includes features such as a wide input voltage range of 12-250V AC/DC, narrow input current range of 0.2-25A (max), and an operating temperature range of -40C to +85C. It is a highly accurate device that offers a linearity error of less than 0.2% and a resolution of 0.02%. Additionally, the CR4820-250 is equipped with a relay output, which can be used for light and motor protection, as well as other control needs. The output of the device is used to switch between two ports or levels, providing a smooth transition from one level to the next.

The working principle of the CR4820-250 is based on two integrated circuits (ICs) that work together to measure input current and voltage. The first IC, a voltage regulator, generates a constant voltage across the two terminals of the transducer. The second IC, an analog-to-digital converter, is used to convert this generated voltage into digital data which is then processed by the microcontroller to display the measured value. The output of this microcontroller is then used to activate the relay output to switch between two ports or levels.

The CR4820-250 is a reliable and accurate device that can be used for a variety of applications in a wide range of industries. It can be used for motor control, power monitoring, and lighting control, as well as for detecting over-current, over-voltage, and low-voltage conditions. In addition, the device can be used in combination with other systems such as controllers and sensors to create a complete monitoring and control system.
