215U-2 WiFi IoT I/O Gateway

SKU: UCE-215U-2

The Elpro 215U-2 now supports MQTT with SparkplugB. This takes a huge step forward in enabling UHF telemetry devices to make use of exciting IIoT functionality.

The 215U-2 configuration is quick and easy using built-in Webbased tool either directly at the unit or over the air, which also provides comprehensive diagnostic features.


ELPRO industrial wireless has 30 years of expertise in solving critical industrial applications through our extensive knowledge in wireless I/O, modem and gateway applications. The 215U-2 extends communications to sensors in local, remote, and difficult-to-reach locations using a 802.11 b/g/n based standard.

The internal radio transceiver is designed to operate reliably with the challenges of obstructed paths, typical of remote monitoring and control applications. Supporting base and ProMesh meshing functionality, the 215U-2 provides for reliable redundant networks in industrial applications.

The 215U-2 I/O Gateway now enables your devices to access the “Internet of Things” (IoT) and Industrial 4.0 connectivity solutions.
Now equipped with MQTT and SparkplugB, the 215U-2 easily provides powerful and versatile IoT Gateway functionality at your outstation. The 215U-2 outstation now has the ability to connect directly to a broker without the need for an additional MQTT edge gateway.

Connect local I/O or external devices PLC’s/ Flow meters/ sensors via Modbus TCP or RTU via its internal Modbus gateway and have timestamped data ready to be sent via MQTT.
The 415U-2 supports Store and Forward functionality which in the event of a communications failure to the broker will Store timestamped event data locally, and automatically Forward the data when the connection is reinstated to the broker. Built for industrial applications the need for redundancy is important, therefore up to four MQTT brokers/servers can be configured
