Cost-effective wireless pulse counter, input signal transmitter for industrial companies and utility providers.

It is receiving and counting incoming digital signals (contact/voltage/pulse) of connected meters (1 to 8 water or gas meters), measurement devices – through IO port.

The communicator is providing wireless data transmitting through the LTE 450 mobile network to the data center.

Suitable for answering Modbus RTU request of a Scada system, where it is responsing meter count data towards to the centre.

It is also useful for remote monitoring of inputs (external device current status) and for output control (remote switch or gate opening).

Easy to configure (remote, local by a free tool), easy to use. The communicator can be accessed remotely.

The data evaluation can be performed in the server side (Cloud) in the Client’s platform.
