Communication modules
Modules in general
To adapt the meter for various applications SonoSelect 10 and SonoSafe 10 features a slot for mounting
communication modules.
Each module features its own µ-controller and is powered by its own battery.
Modules have their own parameter set which is saved in the module µ-controller flash memory. A local
copy of the energy meter parameters used for communication is stored in the module.
Data from module is updated in meter every 10 minutes.
Power: Lithium Thionyl Chloride battery (half of AA size).
2 pulse inputs have common ground.
Modules are galvanically isolated from energy meter circuitry
Wired M-Bus module with 2 pulse inputs
Once installed the meter will display the icon for wired communication and pulse inputs in loop 2 of the
display.
Wired M-Bus is galvanically isolated from μC and pulse inputs.
The two pulse inputs can be programmed independently of each other (see specification for pulse input
module).
