ABB AI930B 3KDE175512L9300 Analog Input HART (AI4H-B). The AI930B Analog Input (AI4H-B) provides input and power supply for 4...20 mA loop powered 2-wire transmitters. It has 4 channels and can transmit HART frames via the fieldbus. It also has cyclic HART variables. The AI930B has electrical isolation between input / bus and input / power, and a common return for all inputs. It also has short and break detection and extended diagnostics. The system is sturdy, error-tolerant, and easy to service. The integrated disconnection mechanisms allow replacement during operation, meaning that there is no need to interrupt the primary voltage to exchange the power supply units. The AI930B is certified for installation in Zone 2 and has G3-coating for all components. It also has simplified maintenance with auto-diagnostics .
The AI930B has dimensions of 20 mm (0.79 in.) width, 104 mm (4.09 in.) depth, and 104 mm (4.09 in.) height. It weighs 0.14 kg (0.31 lbs.) .
The AI930B is an I/O module that can be used with the S7-1200 programmable controller. It is used for connecting intrinsically safe field devices installed in Zone 2, Zone 1, or Zone 0. The AI930B can be installed directly in the field, which reduces the costs for marshalling and wiring. This makes it an attractive option for applications that require a large number of I/O points. The I/O system communicates with the control system level using the PROFIBUS DP standard. The system is easy to configure and diagnose via FDT/DTM.
