Wireless Input/Output (I/O)

Wireless I/O, or Radio Telemetry, is a method of transmitting information over wireless links. Signals such as switch status or analog signals can be transmitted from a remote location to a monitoring or control system. Simple, Robust and Reliable.


Wireless I/O connects directly to analog, discrete and pulse transducer signals. The signals are transmitted by radio using ELPRO’s intelligent wireless protocol. The signals are either re-created as output signals, or output via serial link or field-bus.


GSM/GPRS Modems & Routers

GSM/GPRS Modems and Routers are a perfect complement to ELPRO wireless solutions, allowing customers to remotely access their networks and is a perfect tool for troubleshooting and diagnosing network health.

The perfect solution for remote monitoring and control of critical customer assets, using reliable and proven cellular network technology.
