4 Product Overview
4.1 SMA Sensor Module
The SMA Sensor Module is a module for SMA inverters. The SMA Sensor Module has different
interfaces for connecting various sensors. The SMA Sensor Module converts the signals of the
connected sensors and transmits them to the inverter. The sensors are not included in the
SMA Sensor Module's scope of delivery.
The SMA Sensor Module has the following interfaces:
• 2 temperature inputs for connecting the temperature sensors (e.g. module temperature sensor,
external temperature sensor)
• 1 analog input for voltage or current signals (e.g. of an irradiation sensor)
• 1 supply voltage for a signal source (e.g. of an irradiation sensor)
• 1 S0 interface (e.g. for connecting an anemometer or energy meter)
The SMA Sensor Module performs the following tasks:
• Receive measured data from Pt100 or Pt1000 temperature sensors
• Receive measured data of an irradiation sensor that can output current or voltage signals as
well as provide supply voltage for this irradiation sensor
• Receive measured data of a remote terminal (e.g. anemometer or energy meter)
