Fronius Sensor-Card retrofit IG 4,240,004,Z

The Fronius Sensor Card Retrofit IG 4,240,004,Z is a DATCOM plug-in sensor interface designed to expand compatible Fronius inverter monitoring systems with environmental and system measurement capabilities. Installed as a plug-in card, the Sensor Card provides connections for external sensors so operating conditions surrounding a photovoltaic system can be measured and incorporated into system monitoring.

The Sensor Card supports a total of six measurement signals, including two Pt1000 temperature sensor inputs, one irradiance sensor voltage input, two digital inputs, and one analog current input. This allows a compatible Fronius system to collect information such as module temperature, ambient temperature, solar irradiance, wind speed, and energy consumption. 

As part of the Fronius DATCOM architecture, the retrofit card provides a practical way to add detailed sensor-based monitoring to supported Fronius IG installations without requiring a separate standalone sensor interface.

Key Technology

• Six Measurement Signal Inputs
  Provides six dedicated measurement channels for collecting environmental and electrical sensor data from a PV installation.

• Dual Pt1000 Temperature Inputs
  Two temperature channels support Pt1000 temperature sensors, allowing measurement of both solar module and ambient temperature.

• Solar Irradiance Monitoring
  Includes an analog voltage input designed to analyze the voltage signal produced by a compatible irradiance sensor.

• Wind Speed Monitoring
  Digital input functionality allows connection of a compatible wind speed sensor, with the Sensor Card calculating wind speed from the sensor's pulse frequency.

• Energy Consumption Measurement
  A digital input can be connected to the pulse output of a compatible electricity meter, enabling energy usage to be calculated from the number of recorded pulses.

• 0–20mA / 4–20mA Analog Input
  Supports sensors using standard current interfaces, with selectable measuring ranges of 0–20mA or 4–20mA. 

• Configurable Digital Inputs
  Provides two digital input channels, D1 and D2, for analyzing voltage pulses from devices such as electricity meters and wind speed sensors.

• Integrated +5V Sensor Supply
  A +5V connection is available for compatible digital sensors that do not have their own external power supply.

• DATCOM Plug-In Card Design
  Designed as a retrofit plug-in card for integration inside compatible Fronius inverter hardware, helping reduce the need for separate external monitoring equipment.

Best Uses

• Fronius IG System Monitoring Upgrades
  Ideal for adding sensor measurement capability to compatible existing Fronius IG inverter installations.

• PV Module Temperature Monitoring
  Supports a Pt1000 sensor for tracking solar module temperature and evaluating PV operating conditions.

• Ambient Temperature Monitoring
  A second Pt1000 channel can be used to monitor outside or ambient temperature.

• Solar Irradiance Measurement
  Suitable for installations that need irradiance data to compare available sunlight with actual PV system production.

• Wind & Energy Monitoring
  Digital channels can support wind speed and electricity meter pulse inputs for expanded system performance analysis.
