Tinycontrol INA740 - I2C digital power monitor for measuring current, voltage, power and energy - for DIN rail mounting
The INA740 DIN-rail digital power monitor is an advanced measurement module equipped with an integrated shunt and a 16-bit delta-sigma analog-to-digital converter. It enables precise, bidirectional current measurement up to ±24 A and voltage measurement in the 0 V to 85 V range . The monitor reports key power parameters such as power, energy, bus voltage, and system temperature . Communication via the I2C bus and an RJ connector make the sensor fully compatible with the LK4 controller and other platforms, such as Arduino .

Product description: Tinycontrol INA740 - I2C digital power monitor for measuring current, voltage, power and energy - for DIN rail
The INA740 is a digital power monitor equipped with an integrated current sensing element and a high-performance 16-bit delta-sigma converter , ensuring accurate electrical parameter measurements. The module is designed for direct mounting on a standard 35mm DIN rail . It enables bidirectional current measurement up to ±24A and voltage up to 85V , while simultaneously calculating the power and energy consumed by the load. Additionally, the monitor provides integrated circuit temperature measurement, and I2C communication ensures easy integration with the LK4 controller, Arduino , and other systems equipped with this interface. A four-position switch allows for changing the I2C address and operation of up to four modules on a single bus.
