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) or Mains power supply (230 V). 2 pulse in/outputs have common ground.

Modules are galvanically isolated from main 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 µ-controller and pulse inputs. The two pulse inputs can be programmed independently of each other (see specification for pulse input module).
