Turnkey MQTT broker for the control cabinet

MQTT Box photo

On-Prem solution for the DIN rail

The MQTT.box is a Mosquitto MQTT broker on its own hardware, conformal to industrial standard, for DIN rail mounting.

The user management enables multi-user operation. Building upon this any user can be given specific read and write authorization using the Access Control List (ACL). Together with encrypted communication the MQTT.box thereby meets the requirements for high security applications.

The MQTT protocol enables communication among automation devices as well as linkage to higher levels. The second network interface of the MQTT.box allows coupling of various network segments without permitting access to the other respective sub-network.
