The Acromag NTW2110 is a Wireless Remote Digital I/O Module. Firstly, it connects discrete field signals. Such as relay contacts, switches, and alarm outputs directly to PLC, SCADA, and IIoT systems over secure Wi-Fi Ethernet networks. It provides 16 bidirectional digital I/O channels to monitor and control on/off signals. It suits distributed infrastructure and industrial control use.It is ideal where Ethernet cabling is hard or impractical to install.
Part of the Acromag BusWorks NT remote I/O platform, the NTW2110 supports Modbus TCP, EtherNet/IP, PROFINET, OPC-UA, MQTT, and REST APIs. Systems can expand to 64 mixed I/O channels using NTX expansion modules under a single IP address.
Key Features
- 16 bidirectional discrete I/O channels for monitoring relay contacts, switches, and alarm signals
- Active-low inputs and sinking transistor outputs (up to 32 VDC) suitable for industrial control cabinets
- Integrated dual-band Wi-Fi Ethernet connectivity (2.4 GHz / 5 GHz). Perfect for remote panel monitoring without installing new network cabling
- Includes an RJ45 Ethernet port for local configuration, commissioning, and troubleshooting alongside its primary Wi-Fi Ethernet network interface
- Direct integration with PLC, SCADA, and IIoT systems without requiring external gateways
- Supports Modbus TCP, EtherNet/IP, PROFINET, OPC-UA, MQTT, and REST APIs
- Expandable to 64 mixed signal I/O channels using NTX expansion modules under a single IP address
- Built-in edge logic supports event-based local control without additional PLC programming
- Rugged DIN-rail mounting design with operating temperature range −40 °C to +70 °C for infrastructure and industrial environments
Supported Industrial Protocols
The NTW2110 Wireless Remote Digital I/O Module integrates easily into existing automation environments using:
- Modbus TCP
- EtherNet/IP
- PROFINET
- OPC-UA
- MQTT
- REST API
This allows connection to PLC platforms, SCADA systems, and IIoT monitoring architectures without additional protocol converters.
Expandable BusWorks NT Remote I/O Architecture
The NTW2110 operates as a wireless interface module within the Acromag BusWorks NT modular 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. The wired compatible product for this version is the NT2110.
Systems can support up to 64 mixed digital, analog, and temperature I/O channels under a single IP address. Therefore, simplifying cabinet-level monitoring across both wired and wireless infrastructure environments.
