Introduction
Current transducers are used to measure the currents in electrical systems or to measure the current passing through electrical components. The HX 20-P current transducer is a two-channel current transducer designed for medium- to high-powered applications. The HX 20-P is an easy-to-use, basic, low-cost current transducer suitable for use in many different types of applications such as industrial process control, power distribution, office equipment, automotive, and home appliances.

Analog Output
The HX 20-P current transducer features a two-channel, isolated 4-20mA/0-10V analog output. The two isolated outputs, called A and B, provide simultaneous, but isolated measurements of two separate loads. Each of the two outputs can be configured for either voltage or current output, and the output range is software-selectable. The two outputs are isolated from each other and can operate from either 10V or 20mA. The HX 20-P also features an adjustable analog output. With an adjustable output mode, you can calibrate or match the output from the transducer to the equipment it is connected to.

Digital Input/Output
The HX 20-P also comes with a built-in digital input and output port. The digital input port supports pulse width modulation (PWM), which is used to select either the 4-20mA or 0-10V range for the analog measurements. The digital output port is used to control external devices such as relays, motors, and solenoids. Both the digital input and output ports are isolated from each other, making the HX 20-P an ideal solution for applications that require multiple digital inputs and outputs.

Power Supply
The HX 20-P current transducers come standard with a wide input power supply range (11-36 VDC) making it usable for a variety of applications. The HX 20-P can also be powered by an external power supply with a maximum voltage of 24VDC. The power supply is reverse polarity and over current protected to prevent damage to the transducer.

Measuring Range
The HX 20-P current transducer is capable of measuring up to 600V peak and up to 20A RMS. The transducer is rated for a maximum current of 10A rms for the analog output and up to 10A/phase for the digital output. The high side, low side, and common mode current measuring ranges are 0-10A, 0-5A, and 0-15A respectively. The transducer features a very low (less than 1mA) steady-state current consumption, allowing for accurate measurements in low current applications.

Accuracy
The HX 20-P current transducer is very accurate, with an accuracy of ±0.2% of the reading. The accuracy is verified at both the high and low side of the measuring range. The transducer also features a self-calibration feature to ensure the accuracy is maintained over time. The self-calibration feature can be used to periodically recalibrate the transducer for maximum accuracy.

Conclusion
The HX 20-P is a two-channel current transducer designed for medium- to high-powered applications. The transducer features a two-channel analog output, digital input and output ports, an adjustable output range, and excellent accuracy. The wide input power supply range makes it suitable for many applications, while the self-calibration feature ensures accuracy is maintained over time. The HX 20-P is an easy-to-use, basic, low-cost current transducer suitable for many different types of applications.
