New I/O modules offer dual-band Wi-Fi connectivity to link sensors and actuators to control networks in locations where cabling is impractical.

Acromag, a leading manufacturer of industrial I/O solutions, has announced the release of its new BusWorks® NTW Series Wireless I/O modules. These units expand the popular NT Ethernet I/O family with secure Wi Fi connectivity for remote monitoring and control applications. The NTW Series enables engineers and system integrators to connect sensors and actuators to control systems without running network cabling, making it ideal for applications where wiring is difficult or costly. Each NTW module combines Acromag’s proven NT modular I/O architecture with dual band 2.4 GHz and 5 GHz Wi Fi communication based on IEEE 802.11 a/b/g/n standards.

NTW communication modules support Acromag’s full range of NTX expansion I/O modules, allowing users to append additional channels or signal types. Up to 64 I/O points can be managed over a single IP address. Available I/O options include discrete I/O, analog voltage or current, and temperature, enabling customized signal mixes at each installation point.

“Wireless connectivity opens new possibilities for deploying NT Series I/O in remote and hard to reach locations,” said Robert Greenfield, Acromag’s Director of Business Development. “The NTW Series gives users a simple and cost effective way to extend industrial I/O systems beyond the limits of traditional Ethernet cabling.”.

In addition to Wi Fi connectivity, NTW models include an Ethernet RJ45 port, allowing units to be daisy chained when a wired connection is preferred or available. This hybrid approach gives users flexibility to deploy wired or wireless networking as application requirements evolve.

The NTW Series supports common industrial Ethernet protocols including Modbus TCP/IP and EtherNet/IP, along with peer to peer communication. NTW modules also support IIoT connectivity, including OPC UA and MQTT, with a built in RESTful API for integration with modern data systems.

Security features include WPA3 Wi Fi security, TLS 1.2 with PKI and X.509 certificate management, and AES 256 bit encryption to help protect data transmitted over wireless networks.

NTW modules are housed in a slim 25 mm DIN rail mountable enclosure with pluggable terminals and are designed for reliable operation across wide industrial temperature ranges. The NTW Series has been developed to meet global RF and regulatory requirements, with certifications supporting deployment in multiple international markets.
