Industrial Applications

1. Decentralized I/O Racking in Confined Control Panels

Utilizes the 5-meter cable length to link a primary CS1 CPU rack to an expansion backplane located in an adjacent enclosure.

Problem Solved

Overcomes physical space constraints within a single main control cabinet by safely decentralizing the I/O hardware without sacrificing internal bus speeds.
