Product code:

Wireless communication modem that has been designed specifically for the automatized remote readout of Itron® SL7000, ACE6000, ACE8000 type electricity meters.

The device can be ordered with various wireless module types.

You can save money by using our modem because furthermore there is no need for manual readout of the meter systems.

The device is installable into the enclosure of the meter and it is connectable through its RS232 / RS485 connector.

The modem answers the „Pull” requests of the HES center by transparent data sending through the wireless network. It can send data by CSData call (2G) also.

Suitable for remote readout of registers and consumption data of the connected electricity meters, download of load profile.

The modem is configurable by our WM-E Term® software.

It can be also installed as an external modem by an optional DIN-rail adapter.
