Q: Can AI910B be used in Zone 1 directly?A: No – module is certified for Zone 2 only. For Zone 1, use S900 Type A modules (e.g., AI910A).
Q: Does it support HART protocol?A: No – AI910B is for 4-20mA analog signals only. For HART, choose AI920B model.
Q: How do I power 2-wire transmitters?A: Module provides loop power internally – no external power supply needed for sensors.
Q: Can I hot-swap while PROFIBUS is active?A: Yes – Hot Swap supported. Remove and insert module without interrupting bus communication.
Q: What is G3 coating and why important?A: G3 coating protects against corrosive gases (H2S, SO2). Essential for chemical plants and refineries.
Q: How many AI910B modules per S900 station?A: Up to 20 modules per segment – depends on power budget and PROFIBUS addressing.
Q: Does it work with Siemens PLC?A: Yes – PROFIBUS DP is open standard. Use GSD file for integration.
Q: What’s the difference between AI910B and AI920B?A: AI920B adds HART communication. AI910B is basic 4-20mA with diagnostics.

Choose AI910B if you need:
- Basic 4-20mA analog input in Zone 2
- Loop power for 2-wire transmitters
- Hot-swap and online configuration
- G3 corrosion protection
Consider alternatives if:
- Need HART – choose ABB AI920B
- Zone 1 installation – select AI910A (type A)
- RTD/TC inputs – use AI930B temperature module
