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).
