Communicates with NEWSTEO products
Radio receiver for PLC
Radio receiver for integration in a PLC
A Newsteo sensor network can communicate with the receiver wired to a programmable logic controller (PLC). This gathers measurements from wireless loggers.
Wireless loggers keep their standard functioning (periodically wake up and send measurements, alerts if sensor output values are beyond thresholds, and status information).
These pieces of information are held in the internal registers and can be queried at any time by the PLC. It is not necessary to bring the Newsteo radio protocol but only to integrate exchange tables.
Picture of an installation:

Applications
Building Management System : integration for the implementation of a Newsteo sensors’ network (temperature, dry contact …)
Structure monitoring: measurements operated by Newsteo wireless dataloggers (crack meters, temperature sensors …) communicating with a central controller
- Transport monitoring: the receiver is integrated with a geolocation unit, a on-board computer (with or without GPRS return channel for real-time alerts) and transmits the measurements of a datalogger
