Detailed Product Information
The Economics of Keeping a Spare
A Allen-Bradley 1747-L541 costs a few thousand dollars. One day of downtime in natural gas pipeline compressor stations operating unmanned in remote locations costs $10,000 to over $250,000. One avoided outage pays for your spare parts inventory 10 to 100 times over. For critical applications, implement N+1 sparing — one spare for every 3-5 installed units. For high-availability systems, keep at least one cold spare per module type.
How the 1747-L541 Is Used in the Field
This central processing unit sees service in natural gas pipeline compressor stations operating unmanned in remote locations. Our customers typically install these in Allen-Bradley systems where reliability is non-negotiable.
