ABB CI801 Field Communication Interface

Description

ABB CI801 Field Communication Interface is a field communication interface module designed for industrial automation systems. While direct technical specifications for the CI801 model are not available, it aligns with ABB’s S800 I/O module ecosystem, which features standardized design and functionality. Related S800 series modules, such as the AI815 analog input module, offer reference for typical capabilities: 8 configurable analog inputs that support voltage or current signals, with nominal ranges including 0(4)…+20 mA and 0(1)…+5 V, plus HART pass-through functionality for communication with smart field devices.

S800 series I/O modules, including compatible interface units like the CI801, feature an open-vented plastic enclosure, front-panel LED indicators (fault, run, warning) for real-time status monitoring, and mechanical keying between modules and Module Terminal Units (MTU) to prevent misinsertion and damage from excessive voltage or current. Electronic ID verification ensures modules only operate if their configuration matches the ModuleBus host settings, supporting both single and redundant system setups. Current input channels in the series can withstand transmitter power supply short circuits without damage and are compatible with HART communication protocols, making them suitable for harsh industrial environments requiring reliable field data transmission and control.
