Unknown availability
Precise digital power monitor with integrated current sensor and 16-bit delta-sigma ADC converter.
INA740 is a dedicated 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 supports up to ±35 A) while supporting common-mode 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 supported by the LK4 controller.
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), you need to check the RJ connector pinout, which is described 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 makes it possible to operate up to 4 sensors on one I2C bus, a feature available with the LK4 controller.
Easy installation
The sensor supports mounting on a standard 35 mm DIN rail, making it easy to install in industrial distribution boards and control systems. The device is compatible with wires with a diameter of 0.5-2 mm (12-24 AWG) for flexible wiring.
