The Acromag NTW2210 is a Wireless Remote Analog IO Module. Firstly, it is designed for distributed monitoring of industrial process instrumentation. Especially, where wired Ethernet infrastructure is unavailable or difficult to install. It provides eight differential current inputs. Along with true 16-bit A/D conversion. Therefore, enabling accurate acquisition of 4–20 mA signals from field transmitters and instrumentation devices.
The module also includes two bidirectional discrete I/O channels for additional control or monitoring signals. Plus it supports secure Wi-Fi Ethernet networking for integration into modern automation environments.
As part of the Acromag BusWorks NT modular remote I/O platform, the NTW2210 can expand to support up to 64 mixed analog, digital, and temperature I/O channels under a single IP address using NTX expansion modules.
Key Features
- Eight differential current input channels for 4–20 mA transmitter monitoring

- Includes RJ45 Ethernet port for local configuration and commissioning
- Supports integration with PLC, SCADA, and IIoT monitoring platforms
- Compatible with Modbus TCP, EtherNet/IP, PROFINET, OPC-UA, MQTT, and REST API
- Expandable to 64 mixed signal I/O channels using NTX expansion modules
- DIN-rail mounting for industrial control cabinets
- Wide operating temperature range −40 °C to +70 °C
Supported Industrial Protocols
The NTW2210 Wireless Remote Analog IO Module integrates directly with automation systems using:
- Modbus TCP
- EtherNet/IP
- PROFINET
- OPC-UA
- MQTT
- REST API
This allows direct connection to PLC platforms, SCADA software, and cloud-based monitoring systems without external gateways.
Expandable BusWorks NT Remote I/O Architecture
The NTW2210 operates as a wireless interface module within the Acromag BusWorks NT modular remote I/O system.
A BusWorks NT node consists of either:
- an NTW wireless interface module, or
- an NTE wired Ethernet interface module
combined with optional NTX expansion I/O modules to increase channel capacity.
Systems can support up to 64 mixed signal I/O channels under one IP address, simplifying distributed cabinet monitoring across wired and wireless infrastructure environments.
Equivalent wired Ethernet connectivity is available using BusWorks NTE interface modules where wireless networking is not preferred or permitted. The wired compatible product for this version is the NT2210.
