I. Product Description
Brand: ABB
Full model: NAIO03F
Material code: 3AUA0000016677
Product type: ACS800 frequency converter dedicated general analog I/O expansion module, externally mounted DIN rail installation, communicates with ACS800 main control unit via optical fiber bus; used to expand external analog acquisition and adjustment output points of the frequency converter, connect on-site analog signals such as temperature, pressure, level, valve setpoint, etc., to achieve closed-loop process regulation of the frequency converter, suitable for single drive and multi-drive complete machine systems of ACS800.
Product performance
8 input and 4 output integrated analog expansion, with a single module capable of simultaneously collecting multiple types of sensors and outputting adjustable signals, significantly reducing the number of I/O modules in the control cabinet.
Universal AI across all channels, with software allowing free switching between current, voltage, thermal resistance, and thermocouple on a single channel, without the need to replace hardware to adapt to different sensors.
High isolation and anti-interference design, with fiber optic isolation from the frequency converter main control, avoiding large power frequency harmonic interference, ensuring stable and non-drifting measurement.
Real-time closed-loop regulation, analog signals are uploaded to the frequency converter main control within milliseconds, and can directly perform PID closed-loop speed regulation for pressure, temperature, and flow.
Complete fault diagnosis, fault codes can be uploaded for AI disconnection, AO short circuit, power supply abnormality, and fiber optic communication interruption, enabling rapid troubleshooting of on-site wiring issues.
Compact and lightweight structure, with small space occupied by rail installation, suitable for upgrading and expanding the old ACS800 cabinets.
Full series of firmware compatibility, compatible with all power ranges of ACS800 single drive and multi-drive power units, and the program can be expanded without significant modification.
