ABB AI910S 3KDE175511L9100 Analog Input (AI4-Ex)
The ABB AI910S is an analog input module that is designed to be used with the S900 I/O family system [0]. The S900 I/O family is a remote I/O system used in hazardous-rated areas according to ATEX. The I/O system can be safely located directly in ATEX Zone 1 and 2, saving wiring and signal conditioning costs. The AI910S module is designed to be installed in hazardous area Zone 1 for connecting intrinsically safe field devices installed in Zone 2, Zone 1, or Zone 0. The module has a power supply for 4-20 mA loop-powered 2-wire transmitters and four channels.
The module is designed to be used with the PROFIBUS DP standard, which is a widely used industrial communication protocol that allows communication between devices on a PROFIBUS network . It is important to note that the AI910S module is designed to be used with the S900 I/O family system and may not be compatible with other I/O systems.
The AI910S module is intrinsically safe, meaning that it is designed to limit the energy available for ignition in hazardous areas . This is achieved by limiting the current and voltage levels in the module to prevent sparks or arcs that could ignite flammable gases or vapors .
The module has a width of 20 mm, a depth of 104 mm, and a height of 104 mm. It weighs 0.14 kg and is classified as small equipment (no external dimension more than 50 cm) in accordance with the WEEE directive . The module has a relative humidity maximum of 93% +/- 3% at 40°C, and it can operate in ambient temperatures ranging from -20°C to 60°C .
