Cost-effective wireless input signal receiver and transmitter for industrial companies and utility providers.

The device has two operation modes, but the two modes cannot be used simultaneously*.

a.) Normal mode: It receives and counts the incoming impulse signals of 1-8 connected meters (water or gas) or other measurement devices.

b.) Alternative mode: It receives the voltage/contact signals of the 1-8 inputs of the connected devices.

The communicator provides wireless data transmission to the data center through the Narrow-Band mobile network.

Suitable for answering Modbus TCP request of a Scada system, to which it responds by transmitting meter count data towards the centre.

It is also useful for remote monitoring of inputs (external device current status).

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

Data evaluation can be performed on server side in the client’s software (Cloud).

*Different firmware types are needed for choosing the normal or alternative operation modes.
