Product Introduction
The ABB NETA-21 (3AUA0000093675) is an advanced remote monitoring tool and gateway engineered specifically for ABB industrial variable-frequency drives (such as the ACS800 and ACS880 series).
Equipped with an embedded web server, the NETA-21 enables engineers and maintenance personnel to securely access drive parameters, observe real-time operational data, check active fault logs, and analyze trend graphs via a standard web browser without requiring proprietary software. It supports multi-drive networking through DDCS fiber-optic connections, Modbus RS-485, and Ethernet TCP/IP, allowing a single module to network and monitor up to 32 drives simultaneously for predictive maintenance and remote troubleshooting.

Compliance & Standards Alignment
- Manufactured in accordance with international CE, EMC, and industrial safety directives.
- Engineered to provide high noise immunity against high-frequency electromagnetic interference (EMI) typical of variable-frequency drive cabinets and inverter rooms.
Technical Note: The NETA-21 can utilize an SD card for local data logging, allowing long-term historical trends and fault history to be safely archived for post-incident analysis even if network connectivity to a higher-level SCADA system drops temporarily.
Storage & Asset Preservation Guidelines
- Store the module inside its original factory ESD-shielded packaging to protect internal microprocessors, memory slots, and network transceivers from electrostatic damage.
- Maintain a clean, dry, climate-controlled warehouse environment with relative humidity kept below 85% (non-condensing).
- Avoid mechanical vibration, heavy impacts, or applying physical pressure to the front ports and DIN-rail latch mechanisms.
Physical Installation Prerequisites
- Ensure that power to the control cabinet, auxiliary rails, and connected ABB drive nodes are completely isolated, de-energized, and locked out (LOTO) prior to physical mounting and wiring.
- Snap the unit securely onto a standard DIN-rail, ensuring proper grounding and shielding continuity for Ethernet and RS-485/DDCS fiber-optic communication cables.
- Verify that the 24V DC input power supply polarity and voltage levels are accurate before energizing the device.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this ABB remote monitoring gateway?
A: Industrial communication modules, network gateways, and data processing apparatus typically classify under HS code 8517.62 (Machines for reception, conversion and transmission or regeneration of voice, images or other data) or 8538.90. Confirm final details with your customs broker.
Q: Does the NETA-21 require special software to view drive data?
A: No special client-side software is required for routine monitoring; the device hosts an embedded web server accessible via standard web browsers over an Ethernet connection.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, software license tier, and global logistics status; contact our technical sales desk for a formal, time-sensitive quotation.
