Product Description

The AKH12B-04S sensor is a compact 4-20mA current transducer integrated with Modbus RTU transmitter functionality, designed for reliable industrial monitoring. It features dual-channel input for simultaneous current measurement and supports direct connection to up to 4 compatible modules via its RS-485 interface. Operating within a wide 12-36V DC power range, it functions optimally in temperatures from -20°C to +70°C, suitable for harsh environments in power distribution, industrial automation, and energy management systems. The device offers ±0.5% measurement accuracy with 16-bit resolution and includes galvanic isolation for enhanced EMI resistance. Its integrated Modbus protocol enables seamless PLC integration, while the IP65-rated housing ensures durability. Primary limitations include fixed measurement ranges and dependency on external power. Typical applications include motor load monitoring, transformer current tracking, and smart grid installations.
