sysWORXX SRN-300

Monitoring & control node with long battery life

Mesh Network, Asset Tracking, Monitoring, Control

Since October 2018 we have completed our IoT ecosystem. With the launch of the industrial radio interface sysWORXX SRN-300 and the two controllers sysWORXX CTR-100 and sysWORXX CTR-700 a multitude of solutions can be implemented in a networked industrial environment.


Connect physical quantities of your machine directly to the node

The abbreviation "SRN" stands for Short Range Radio Node. The radio interface is a consistent further development of Meshnet technologies towards industrial applications. The node transmits on a 2.4 GHz transmission frequency and contains an NFC antenna for provisioning.


Standard sensors with standard interfaces such as voltage interfaces of 0...10V, 4-20mA, etc. can be connected directly to the node. This allows any physical quantities that I measure in the machine to be coupled to the node for forwarding to a gateway. You do not have to rely on sensors that can only transmit certain quantities, but you can use the node in many different ways with the help of the industrial interfaces.

Meshnet functionality & long battery life

Because of the integrated software stack of our cooperation partner Wirepas the sysWORXX SRN-300 is suitable for Mesh networks. This integration also enables a long battery life of up to 3 years. This eliminates the need for constant replacement. The node can be connected directly to the sensor or actuator to process the data.

Transmission & control in battery & mains operation

The sysWORXX SRN-300 contains a control function in addition to the transmit function. Due to digital outputs via bistable relays, states can be stored and actuators can be controlled. Depending on its use as a mobile node or as an anchor node in a network, the node can be operated in parallel via battery or via a 24V connection.

Operating data can be read out via the NFC interface for fast configuration of the device and for querying statuses.
