KL3022X1-BA1 | Emerson | AO 4-20mA HART CHARM

Description

The KL3022X1-BA1 Emerson AO 4-20mA HART CHARM is an analog output module designed for industrial automation systems, with key technical specifications derived from comparable Emerson CHARM products. It operates on a DC 12-24V power supply with a maximum ripple of 200mV and a working current of less than 50mA, ensuring stable performance in typical industrial power environments. The module features 4 isolated 4-20mA HART current output channels, supporting HART communication alongside optional Modbus RTU via RS485, with selectable communication speeds including 1200, 2400, 4800, 9600, and 19200 bps to match diverse system requirements. It handles a current loop load range of 230 to 1100 ohms, enabling compatibility with a wide array of field devices. Engineered for harsh industrial conditions, it has an operating temperature range of -20 degrees Celsius to 80 degrees Celsius and a relative humidity tolerance of 10% to 80%. The compact unit measures 135x72x42mm and weighs 141g, making it suitable for space-constrained control cabinets. It may also include passive 4-20mA HART output functionality, and adheres to global safety and quality standards such as ATEX, IECEx, and CE certifications, supporting use in safety-related applications compliant with IEC 61508 and IEC 61511 standards.
