Cost-effective input signal- and consumption meter impulse counter, wireless transmitter for smart metering and input surveillance.

It receives, counts the incoming signals (contact/voltage/impulse) of the connected 1-8 pcs water/gas meters. The data are transmitted on wireless network to the data center.

It is also suitable to answering Modbus RTU requests of a Scada system, to which the device responds by sending meter count data to the centre.

Capable of remote monitoring of input lines (for external devices) and remote output control of max. 4 external devices (switching or gate opening).

It emits periodical life signals, has detection and notification capabilities of wire cut and sabotage.

The device can be ordered in CDMA 450 / 2G / 3G / LTE 4G / Narrow-Band versions.

Event notification by SMS text messages.

It is easy to configure (remote, locally by a free tool), easy to use. The communicator can be accessed remotely.
