1 .1 Description of GSM7i
•
GSM/GPRS module for a fast and stable reading of the electricity meter
•
Innovative solution that future-proofs the metering point via extra module
area
•
Plug and play installation with clear information about the signal strength
•
Status/pulse input
•
Relay output for controlling external units (load control)
•
SMS reading of meter and GSM signal strength
•
Internal antenna.
The GSM7i module differs from earlier GSM modules in that it
can only be placed in ”J” meters, i .e . the Kamstrup electricity meters
that have internal supply for the module .
Application
With the module GSM7i, the metering point is future-proofed since the module
supports GSM, GPRS and SMS. In addition, it is possible to mount an extra
Add-on module. On this Add-on module, it is possible to add extra features
(e.g. load control relays) or an additional communication media (e.g. ZigBee,
Z-Wave, Wireless M-Bus or similar).
The module GSM7i is mounted directly in the module area of the electricity
meter (162J, 282J, and 382J), which makes it possible to read and configure
the meter remotely. The quality of the installation is ensured by means of
informative Light Emitting Diodes (LEDs) that indicate the GSM signal strength.
Likewise, it is possible to read the signal strength by SMS in order to be able to
check installations in closed cabinets.
