ABB AI815 High-Precision Analog Input Module for Industrial Automation
Description
ABB AI815 High-Precision Analog Input Module is a high-precision analog input module for industrial automation, part of the ABB S800 I/O series. It converts field sensor signals such as temperature, pressure, and flow into digital signals for controller processing, and supports HART protocol communication for use in harsh industrial environments.

Key Features:
- Multi-channel signal compatibility, configurable for voltage or current input (no mixing of signal types on one module)
- HART pass-through communication for direct connection with smart transmitters, simplifying debugging and maintenance
- Comprehensive input protection: PTC current limiting for current inputs (withstands 30V overvoltage), high impedance for voltage inputs to reduce interference
- Industrial modular design compatible with DIN rail mounting and various MTU units like TU810, TU830
- Built-in self-diagnosis to monitor internal power, memory, and external transmitter power faults; supports redundant power input in some configurations
Applications:
- Industrial process control for chemical and pharmaceutical production line monitoring
- Energy management systems for power equipment energy consumption analysis
- Distributed control systems for remote signal collection with AC800M controllers
- High-precision laboratory equipment signal acquisition
