ABB AI05 AI05A 2-channel isolated analog input module

The AI05 HART analog input module is designed to process up to 8 high-level analog field inputs for a Symphony Plus controller. It is equipped with additional features compared to the AI02 module, providing higher performance. The Symphony Plus controller uses function code 221 (I/O Device Definition) for module configuration and function code 222 (Analog In/Channel) for configuring and accessing each input channel. Each channel on the AI05 module can be individually programmed for current or voltage inputs.

Key features and enhancements of the AI05 module compared to AI02:

1. Individual Channel Isolation: The AI05 module provides individual channel isolation, enhancing the overall performance and reliability of the system.
2. Dedicated HART Modem and A/D Converter per Channel: Each channel on the AI05 module is equipped with a dedicated HART modem and A/D converter, allowing for more precise and efficient processing of high-level analog signals.
3. Support for up to 32 Secondary Variables: The AI05 module supports up to 32 secondary variables, providing expanded capabilities for monitoring and control.

Base Compatibility:

• The AI05 module can be used with HBS01-EPD or VBS01-EPD base options.

Termination Units:

1. NFTP01 (Field Termination Panel): Used for mounting termination units inside a 19” rack-style cabinet. One NFTP01 can accommodate two termination units.
2. NTAI05 (Analog Input Termination Unit): Provides a signal path between 15 input signals from the field and the SPFEC analog input module.
3. NTAI06 (Analog Input Termination Unit): Provides signal paths between 16 input signals from the field and the SPASI analog input module.
4. NTCL01 (Communication Termination Unit): Terminates the control network (Cnet) connection to the SPNIS module, supporting twinaxial or coaxial cable connections.
5. NTCS04 (Termination Unit): Provides connections for the SPCIS and SPQRS modules.
6. NTDI01 (Digital Input Termination Unit): Provides signal paths between 16 digital input signals from the field and the SPDSI, SPDSO, and SPDSM modules.
7. NTDI02 (Hot Switch Termination Unit): Provides signal paths for 16 signals from the field and the SPDSI, SPDSO, SPDSM, and SPASO modules.
8. NTDO02 (Digital Output Termination Unit): A 16-channel digital output termination unit that works with the SPDSO digital output module.
9. NTMP01 (Multi-function Processor Termination Unit): Used with rack-mounted controllers, providing serial communication ports for a Harmony Rack controller and Cnet-to-Cnet communication interface.
10. NTST01 (Termination Unit for SOE Applications): Used with SOE applications and can be used with the SPTKM or SPSET modules.

These components together form a comprehensive system for analog input processing and control within a Symphony Plus environment. If you have any specific questions or need further clarification on any part of this information, feel free to ask!
