GPRS Alarm Modem

The GPRS Alarm Modem is designed to collect messages that are detected as activated switching contacts and analog limit values. Communication with the server is performed over a virtual dedicated line via GPRS as a point-to-point, multipoint or multi-drop connection. An Internet exchange server may log the states of the inputs and outputs permanently on the basis of event or time control. The server constitutes a relational database, i.e. external access is possible via SQL queries.

The exchange server is a service provided by Weidmuller.

The configurable alarms are issued via SMS, e-mail, voice messaging and/or fax. The IE-GPRS-I/O implements telecontrol by remote-switching of the outputs via telephone/mobile telephone. The IE-GPRS-I/O can be teleserviced and remote-configured. The Weidmuller GPRS I/O has an aluminum housing just 45 mm wide and the following configurable features:
