Current transducers are devices used to measure electrical current. They’re used by engineers and technicians in various electrical engineering disciplines including energy analysis, fault protection, and power quality management. An important type of current transducer is a control-loop transducer, such as the SI8513-C-IS. This article will discuss the SI8513-C-IS, including its application field and working principle.

The SI8513-C-IS current transducer is an integrated current sense solution for digital industrial process control applications. It provides high accuracy, flexibility and reliability in a small package. The device is suitable for measuring current in high power industrial equipment such as pumps, motors, compressors, and other loads. It can also be used in regenerative applications such as battery charging, wind and solar power generation, and motor-generator sets. The transducer is designed for use in industrial networks such as PROFIBUS-DP, Ethernet/IP, and MODBUS. It is also easy to integrate into a variety of distributed control systems.

The device features a power-supply range of 10 to 32 VDC, an accuracy of 0.25% of nominal current, and a nominal full-scale current range of 0.2 to 10A. It also features an integrated blanking function that can reduce the response time of the transducer to measured current. This reduces the lag due to the current sampling loop and ensures faster control loop response. The device also features an adjustable threshold voltage that can be used to set the maximum level for the measured current. It also features an open-collector output and a built-in magnetic fuse for added protection.

The working principle of the SI8513-C-IS current transducer is based on the Hall effect. The unit is composed of a circuit board, an integrated Hall element, and a power supply. The Hall element senses the current passing through the board and generates a magnetic field proportional to the current. This field is detected by the Hall element, which produces an analog voltage. The analog voltage is then amplified and converted to a digital signal by the transducer’s integrated signal conditioning and conversion circuitry. The digital signal is sent to a digital input, where it is processed according to the needs of the application and the parameters that have been set.

The SI8513-C-IS current transducer is a compact, reliable, and high accuracy current measurement solution for industrial applications. It is designed for fast response, high accuracy, and a wide range of applications. The integrated features and adjustable thresholds make it a great choice for a variety of applications including energy analysis, fault protection, and power quality management. The device’s working principle, based on the Hall effect, ensures a fast response, accuracy, and reliability.
