Description
ABB NETA‑21 (3AUA0000093675) Remote Monitoring Tool
Product Overview
NETA‑21, Order code: 3AUA0000093675 is ABB DIN‑rail mounted remote monitoring gateway for ABB low‑voltage variable‑frequency drives. It integrates embedded web server, multi‑interface drive access, data logging and remote access functions. It collects operational data, fault records and parameter values from multiple ABB drives, delivers data via Ethernet to local web‑browser clients or ABB Ability cloud platform, supporting preventive maintenance and remote drive diagnostics without extra PC softwareABB Group. NETA‑21 supports multi‑drive connection via DDCS fiber, Modbus RTU, Panel‑Bus and Ethernet, maximum up to 32 drives per unitABB Group. NEXA‑21 is the matching fiber‑optic expansion module for ACS800 series drives.
ABB NETA‑21 3AUA0000093675
Typical Applications
- Drive fleet remote monitoring: Central monitoring for multiple ABB drives in water‑treatment, mining, cement, pulp‑paper, HVAC and material‑handling sites
- Preventive maintenance: Log drive runtime, energy consumption, temperature, fault events and parameter changes for predictive service
- Web‑based local access: Use standard browser (PC / tablet / mobile phone) to read / adjust drive parameters, view real‑time waveforms and fault history
- Cloud‑connected condition monitoring: Connect to ABB Ability platform for remote site supervision (requires outbound internet access)ManualsLib
- Legacy drive system retrofit: Add remote monitoring function for existing ACS800, ACS850, ACS880, ACS355 series drives
- Unattended site deployment: Remote troubleshooting for pumping stations, fan groups and distributed unmanned workshops
