ABB AI930N 4-Channel Analog Input for Non-Hazardous Areas
Product Introduction
The ABB AI930N belongs to the S900 I/O Type N family. Engineers use this module in safe (non-hazardous) areas only. It connects to 4-20mA loop-powered 2-wire transmitters with ease. Additionally, the module supports HART frames via the PROFIBUS DP fieldbus. You can also access cyclic HART variables for advanced process data.
One major benefit is hot swap functionality. You can replace the 3KDE175513L9300 during operation without powering down. The module also includes short and break detection. This feature simplifies troubleshooting significantly. Furthermore, the design offers electrical isolation between input/bus and input/power. Therefore, it provides reliable signal integrity in industrial environments.
Key Technical Specifications
The ABB AI930N provides four analog input channels. All channels share a common return. The signal type is 4-20mA. HART communication is fully supported. However, this module does not include intrinsic safety. You must install it only in non-hazardous locations.
Redundancy for power and communication is not available on this variant. Nevertheless, the module supports hot configuration in run. This allows parameter changes while the system operates. Extended diagnostics are also built in. You can configure and monitor the 3KDE175513L9300 easily using FDT/DTM tools.
Environmental and Mechanical Data
The AI930N carries a CE mark for European compliance. It also meets ISA-S71.04 G3 standards for corrosive atmospheres. Climatic operating conditions allow up to 93% relative humidity at 40°C. The maximum ambient temperature ranges from -20°C to 60°C.
Dimensions are very compact. Width equals 20 mm (0.79 in.). Depth is 104 mm (4.09 in.). Height is also 104 mm (4.09 in.). The module weighs only 0.135 kg (0.297 lbs.). Additionally, it complies with RoHS and WEEE directives. The WEEE category is small equipment with no external dimension exceeding 50 cm.
Frequently Asked Questions (FAQ)
1. Can I install the ABB AI930N in a Zone 2 hazardous area?
No. The AI930N is designed only for safe (non-hazardous) areas. For Zone 2 applications, use the AI930B variant instead.
2. Does this module support HART communication?
Yes. The 3KDE175513L9300 transmits HART frames via the PROFIBUS DP fieldbus. It also reads cyclic HART variables.
3. Can I replace the ABB AI930N while the system is running?
Absolutely. The module offers hot swap functionality. You do not need to interrupt primary voltage.
4. What happens if a sensor wire breaks or shorts?
The module includes automatic short and break detection. It reports the fault through extended diagnostics. This helps you locate issues quickly.
5. Is the ABB AI930N redundant for power or communication?
No, this variant does not support redundancy. However, the S900 system offers redundancy with other modules. Check your system configuration for details.
