This rack-mounted ABB SD Series I/O setup shows the AI02 module alongside similar units, highlighting its compact horizontal row design for control cabinets.

The ABB AI02 analog input module is designed specifically for Symphony Plus distributed control systems, processing 16 high-level analog field signals and supporting HART intelligent instrument communication. A single A/D converter ensures synchronous sampling and built-in protection mechanism enhances system reliability. The modular design is compatible with all SD series bases and is widely used in chemical, power, and oil and gas process control. Keywords: ABB AI02 analog input, Symphony Plus HART module, SD series I/O, 16-channel AI module, 4-20mA HART input, industrial DCS analog acquisition.

AI01: No HART version, dual A/D converter 22.5m/s channel update.

AI03/AI04: Extended voltage range, -10/+10VDC support.

DO02: Comes with a 16 channel digital output module.

Q: How to implement HART communication?

A: Built in 1 HART modem service for two groups (channel 1/9), supporting v5.4 protocol multi device polling.

Q: How fast is the update rate?

A: Update all 16 channels in 100ms, which is 80% faster than AI01's 180ms.

Q: What bases are supported?

A: The xBS01 series is fully compatible (single/redundant, compact/full-size), with mechanical keys to prevent accidental insertion.

Q: On site protection function?

A: 96mA current limit anti short circuit,<5-second open circuit detection, real-time upload of diagnostic data to the controller.
