I2C 4-20mA Current Loop Receiver Module – IS4420-M1

The IS4420-M1 is a high-performance I2C current loop receiver module that simplifies industrial data acquisition. This 8-pin device converts 4-20mA signals into digital I2C data, allowing you to skip complex analog design. It provides the final current value directly to your microcontroller, making it the most efficient way to read industrial analog communications without the hassle of signal conversion or implementation.

SKU: IS4420-M1

Simplify Industrial Data Acquisition with the IS4420-M1

The IS4420-M1 current loop receiver is a specialized 8-pin module that enables any microcontroller to interface with industrial sensors effortlessly. While traditional methods require precision shunt resistors and filtered analog-to-digital converters, this module handles the entire signal conditioning process internally. Consequently, you can read the precise current value or signal percentage directly through a standard I2C interface.

Digital Accuracy for Analog Signals

Designing reliable receiver circuits often involves managing ground loops and signal noise. The IS4420-M1 solves these issues by providing a dedicated digital solution for analog monitoring. Because the conversion happens within the module, your primary microcontroller is shielded from electrical noise. This architecture ensures that the data you receive is both stable and accurate, even in electrically “noisy” industrial environments.

Seamless Industrial Integration

The 4-20mA current loop standard is the backbone of process automation. By using the IS4420-M1, you can integrate professional pressure, temperature, or flow sensors into your digital ecosystem. You no longer need to worry about the mathematical implementation of signal scaling. The module provides the final current value in a format that your firmware can use immediately.

Applications and Compatibility

  • Industrial Monitoring: Connect long-distance analog sensors to modern IoT gateways.

  • PLC Data Integration: Read 4-20mA signals from industrial controllers without expensive analog input cards.

  • Compact Design: The 8-pin form factor is ideal for space-constrained PCB designs.

How does the IS4420-M1 simplify my hardware design? The IS4420-M1 integrates the shunt resistor, filtering, and ADC into one 8-pin module. Therefore, you do not need to design any analog circuitry; you simply connect the current loop and read the data via I2C.

Can I get the signal value in percentage? Yes, the module is designed to provide the current loop information in both raw current values and as a percentage of the total signal range for easier software processing.

Is the IS4420-M1 suitable for long-distance sensing? Absolutely. Since it uses the 4-20mA standard, it is perfect for receiving signals from sensors located hundreds of meters away where voltage-based signals would suffer from significant loss.
