• Equipment manual

Integrate load feeders directly into automation systems using plug-and-play intelligent link modules to achieve field-level transparency and digitalization.

SIRIUS contactors offer the most comprehensive product portfolio on the market for reliably controlling electric drives and motors in any application.

SIRIUS 3RV2 motor starter protectors provide ideal protection for machines and plants by quickly disconnecting equipment to prevent costly damage.

The SIRIUS 3RA8 ILF is a complete, ready-to-use solution for intelligent, digital load feeders. Six perfectly preconfigured, pretested variants that combine a SIRIUS 3RV23 circuit breaker, a matching SIRIUS 3RT20 contactor, and the SIRIUS 3RC7 intelligent link module cover the entire power range from 0.4 to 32 A, with short-circuit withstand capacity up to 150 kA and including direct and reversing starters. Unpack, install, done!

Integrate ILFs directly into your automation system and use real-time status information and energy data directly from the field to enable predictive maintenance, faster error detection, and precise energy and cost analyses per feeder to improve OEE.

Acquire measured values directly and analyze current status information to comprehensively optimize efficiency. Detect and correct errors quickly thanks to integrated diagnostics.

Ensure maximum system uptime through integrated overload protection and rapid fault detection. Identify maintenance needs early to prevent unplanned downtime.

Gain a holistic view of your production down to the field level, configure parameters directly in TIA Portal, and reduce wiring and installation effort during commissioning and expansions.

Connect up to 16 ILFs to a SIMATIC ET 200SP interface and configure them quickly and easily using SIMATIC STEP 7 in TIA Portal, without the need for address configuration or a PC when replacing devices.

Use the SIRIUS 3RA8 ILF to enable seamless communication from the field to the cloud, allowing you to remotely switch load feeders and reactivate them after a fault trip.

Enhance the communication capabilities of your factory equipment with the SIRIUS 3RA8 ILF to gain direct visibility on the factory floor, reduce downtime, and increase plant productivity.

For a control cabinet retrofit at a quarry operated by the amo/Debus Group, DASA Elektronik installed SIRIUS 3RA8 intelligent load feeders. The intelligent load feeders now enable continuous monitoring of current values and collect drive data for long-term analysis, supporting the early detection of potential disruptions and preventing unplanned downtime through optimization and predictive maintenance.

Yes, the SIRIUS 3RA8 is specifically designed to retrofit conventional load feeders into modern automation systems. Its plug-and-play architecture, pre-tested combinations of contactor, circuit breaker, and intelligent link module, and seamless integration with TIA Portal enable quick and reliable installation in existing setups. The pre-assembled design minimizes engineering effort and downtime in a wide range of industrial environments.

Yes. Although optimized for TIA Portal, the SIRIUS 3RA8 can be integrated into third-party systems via standard fieldbus interfaces. When connected to higher-level controllers via the SIMATIC ET 200SP interface, it enables data to be integrated into any control system or PLC that supports PROFINET. This flexibility allows for integration into third-party automation systems and the gradual digitalization of mixed-vendor environments. However, full functionality—such as advanced diagnostics and parameterization—is best utilized within the TIA environment. For non-Siemens PLCs, refer to the technical manual for interface specifications and compatibility.

The SIRIUS 3RA8 provides real-time field-level data such as current and voltage, thermal overloads, energy consumption per feeder, and switching cycle counts. This data is transmitted directly to the higher-level automation environment, enabling the early detection of issues such as worn contactors or motor phase imbalances and allowing for proactive interventions before failures disrupt operations.

Yes, the SIRIUS 3RA8 directly contributes to energy savings through detailed energy monitoring at the feeder level, load management to balance demand, and fault detection to resolve inefficiencies such as phase imbalances or overloads. Data can be exported for comprehensive analysis, enabling operators to identify and eliminate waste, optimize equipment operation, and reduce costs.

Yes. The SIRIUS 3RA8 is a fully preassembled digital load feeder consisting of the SIRIUS 3RC7 intelligent link module, a SIRIUS 3RV23 circuit breaker, and a matching SIRIUS 3RT20 contactor. Available in six pretested versions, it covers the entire power range from 0.4 to 32 A, offers short-circuit resistance up to 150 kA, and includes direct and reversing starters.

This ready-to-use solution provides all the digital features of the intelligent link module, eliminates the need to find suitable combinations on your own, significantly reduces the risk of configuration errors, and simplifies and speeds up the installation process.
