Modbus modem with RS485

Cost-effective, C-rail mountable industrial modem for receiving digital signals and collecting pulse signals of residential meters.

The modem is capable of continuously counting the pulse signals of up to 4 meter systems.

The device transmits the calculated input signal values through Modbus TCP protocol to query servers Modbus TCP.

The queries of the data sets are performed periodically (e.g. in every *5 minutes) depending on the server value set.

When it has to receive signals from more than 4 devices, we suggest using the M2M IO/RS**5 CONCENTRATOR®   which has *2 input lines.

In this case  the device requests the concentrator input counter status through the modems RS**5 interface, and fowards the received Modbus RTU reply through Modbus TCP protocol to query the servers Modbus TCP.

The modem can initiate queries through its RS**5 interface towards several concentrators input lines.

Furthermore, the modem can switch external devices (optionally) with the help of its 2 relay outputs.
