WISE-2211 - Proprietary LPWAN IoT Wireless Self-Powered CT Sensor Node for DC currents


CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.


This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.

Wireless Connectivity

These devices have built in wireless interface controllers enabling them to connect to a wireless network.

DIN-rail mountable

These devices have been designed to be mounted directly on to an industry standard DIN-rail.

FCC Approved

The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.

Wide Temperature

These products utilise high quality industrial grade components enabling them to work in wide temperature environments. They are capable of running as low as -20C and as high as +70C.


Modbus is a communication protocol for transmitting information between electronic devices over serial lines or via Ethernet and is commonly used in process and factory automation.

The WISE-2211 from Advantech is a proprietary LPWAN sensor mode that is self-powered using current from analog inputs. Self-powered LPWAN technology is ideal for sustainable factories and building applications. Powered by a maximum of three CT (Current Transformer), no cables or batteries are required for switching or for collecting power current information from pumps, servers, or machine tools. Self-powered LPWAN networks save resources by using fewer cables and eliminate the need for batteries.

LPWAN is a variety of low-power, wide-area network technologies created for machine-to-machine (M2M) and Internet of things (IoT) networks. LPWAN is a low-cost high power efficiency network technology and has a high penetration rate providing a better connection in comparison to traditional wireless technology.

By using the power over analog input channel design, no wire power installation is needed. WISE-2211 is plug and play for quick deployment into your IoT applications. The current transformer supports a DC power current range from 3A to 60A or 15A to 300A for different current measurement applications.
