Digi WR 31


The router Digi WR 31 is a cellular router dedicated to industrial applications, designed to also work in ATEX zone (Explosive Atmosphere). the Digi WR 31 provides connection to 4G LTE cellular networks, with automatic backup to 3G and 2G networks depending on availability and coverage.

The ModBus support will allow connection and administration through the serial port directly from the deployed PLCs. It is a transparent replacement solution to the removal of PSTN links. 

Likewise the Entries exitsavailable will allow the alarm or information to be raised in real time. Thanks to the on-board Python engine, it is possible to process the data locally so that only the relevant ones are reported.

The ATEX certification on the European LTE model allows deployment in constrained environments without problem.

Likewise the Native Din Rail and the router's power strip simplify its installation in the field.

The Digi WR 31 routers can of course be managed remotely using the platform Digi Remote Manager or via SNMP
