SIRIUS 3RA8 Intelligent Branch Feeders Integrate Conventional Feeders into Automation

Introduction

Communication from the field to the cloud – simply. With the plug-and-play expansion module 3RC7 for SIRIUS Control, you make branch feeders intelligent and connect them directly to automation systems at the field level. The intelligent link modules SIRIUS 3RC7 are part of the SIRIUS system portfolio, the comprehensive range for industrial switchgear. SIRIUS 3RA8 is an already matched, tested combination, a complete solution delivered pre-assembled and pre-tested with a short-circuit rating of 150 kA.

Discover the highlights of the SIRIUS 3RA8 intelligent branch feeders and the SIRIUS 3RC7 intelligent link module:

• More Transparency through communication down to the field level
• More Safety through integrated, proactive functions
• More Efficiency through greatly simplified assembly
• More Automation through integration in TIA (Totally Integrated Automation)

Digitalization Down to the Field – Simply!

Transparency down to the field level is becoming increasingly important, but many devices offer no connection to the automation system. This results in missing data. Siemens is changing this with the compact, intelligent link module SIRIUS 3RC7, which simply clicks between the contactor and circuit breaker and connects to the SIMATIC ET 200SP. It thus forms an intelligent branch feeder 3RA8 – simply digital and multi-intelligently.

The intelligent branch feeders open up entirely new possibilities for planning and engineering, as well as plant operation. Both 3RA8 and 3RC7 can be conveniently configured in TIA Portal and offer useful diagnostic functions. Thanks to their integration into the ET 200SP, branch feeders become part of the automation; devices can be easily expanded and maintained. They bring data transparency down to the field level – with minimal effort.
