Redundancy Adapter Unit for Space-Saving Field Device Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing redundancy connection methods for peripheral devices in automation technology require additional space and multiple cables, making them inefficient for minimizing downtime and complicating the connection of redundant assemblies across spatially separate devices.
Innovation Solution
A redundancy adapter unit that connects field devices to basic modules within peripheral devices using a single cable, eliminating the need for an MTA terminal module and allowing direct contact between basic modules, thereby simplifying the redundancy connection process without additional space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a MTA terminal module is used for redundant connection of field devices, then redundancy is achieved, but additional space is required in switchgear cabinets
Solution Approach 1:
The patent combines the redundancy adapter unit with the basic module housing, integrating the redundancy function into the existing module structure. This eliminates the need for separate MTA terminal modules and their associated space requirements, as the adapter unit is mounted directly on the basic module carrier within the peripheral device housing.
2Reliability
If Y-cabling with two cables is used for redundant connection, then field devices can be connected to multiple assemblies, but the connection process becomes more complex
Solution Approach 1:
The patent extracts the cable management complexity from the redundancy connection system by providing a single cable connection path through the adapter unit. Instead of requiring two separate cable connections for redundancy, the system uses one cable that connects through the adapter unit to multiple basic modules, simplifying the physical connection while maintaining redundant functionality.
3Reliability
If separate MTA terminal modules are mounted on top-hat rails, then redundancy is achieved, but installation requires additional space and mounting infrastructure
Solution Approach 1:
The adapter unit serves multiple functions: it provides redundancy connection capability, mounts directly on existing basic module carriers without requiring separate top-hat rail infrastructure, and enables both signal and power connections through a single integrated unit. This multi-functionality eliminates the need for additional mounting infrastructure and simplifies installation.
