The NIO 31 is the Gateway to Both Serial and Modbus Data Support

Need to transfer raw serial and Modbus data but don’t want to purchase different gateways? The NIO 31 is the two-in-one answer to all of your serial to Ethernet and Modbus/RTU to Modbus/TCP connectivity needs. You can easily configure with Windows utilities to access industrial serial devices at your workplace. The Modbus gateway solution also features a compact, rugged design and wide DC power range.

Two-in-one Features at a Competitive Price

The rapid development of IIoT has arguably increased manufacturing productivity and efficiency by networking applications and automated devices. However, this has concurrently created a mixture of communication methods, including serial to Ethernet and Modbus, that normally require separate gateways to manage and control. The NIO 31 addresses this issue by combining separate serial to Ethernet and Modbus gateways into one, saving you valuable administrative costs.

 

Simple to Connect, Simple to Install

The NIO 31 makes life easy with two serial ports and support for up to 16 Modbus/TCP masters or 32 Modbus/TCP slaves. You can simultaneously connect to a multitude of serial device types, including flow meters, RTUs, CNC machines, barcode readers, power meters, and temperature sensors. The gateway is also user-friendly, as you can easily configure the device via the included Windows utility or the Web.

 

Tiny Size and Wide-range Power

The NIO 31 packs in numerous features but in such a small size that it fits in the palm of your hand, making it easy to find installation space in your work environment. In addition, it comes with your choice of terminal block or power jack, which provides wide-range voltage of 9 to 40 VDC commonly used in industrial fields.
