Precision digital power monitor with integrated current sensor and 16-bit delta-sigma ADC converter.

The INA740 is a specialized sensor designed for accurate measurement of electrical parameters in industrial and IoT applications. The device can measure bidirectional currents up to ± 24 A (connector limit, the chip itself handles up to ± 35 A) with support for a common voltage up to 85 V. Thanks to its high accuracy and wide measurement range, it is ideal for monitoring energy consumption, system diagnostics, and performance optimization.

The sensor provides comprehensive measurements including current, bus voltage, chip temperature, power, and consumed energy. Communication is via the I2C bus and the RJ connector is compatible with Tinycontrol devices, with the sensor being supported by the LK4 controller.

Bidirectional current measurement in the range of ± 24 A with high accuracy
Voltage measurement in the range of 0–85 V for a wide range of applications
Integrated temperature sensor with accuracy of ± 1.5 °C (at 25 °C)
16-bit resolution for highly accurate measurements
Very low internal resistance (shunt) of only 800 µ? minimizes losses
Power measurement accuracy of ± 1.6% and energy accuracy of ± 2.1%
4-position switch for changing the I2C address, allowing operation of up to 4 sensors on one bus
Mounting on a standard 35 mm DIN rail for easy installation

Universal connectivity and integration
The RJ connector of the sensor is compatible with Tinycontrol devices, and the sensor is supported by the LK4 controller. For integration with other controllers (e.g., Arduino), it is necessary to be familiar with the RJ connector pinout, which is described, for example, in the short LK4 manual.

Flexible I2C addressing
The sensor board is equipped with a 4-position switch that allows changing the I2C address. This enables up to 4 sensors to operate on one I2C bus, a feature available with the LK4 controller.

Easy installation
The sensor supports mounting on a standard 35 mm DIN rail, which simplifies installation in industrial cabinets and control systems. The device is compatible with wires with a diameter of 0.5–2 mm (12–24 AWG) for flexible wiring.
