Curtiss-Wright / ACRA Control KAM/CHS/06U/E/00 6 User-Slots KAM-500 Chassis

The Curtiss-Wright/ACRA Control KAM/CHS/06U/E/00 is a 6-user slot KAM-500 chassis that provides a modular platform for data acquisition and control in demanding aerospace and defense applications. Built around an 8 MHz × 16-bit digital backplane, this system accepts any combination of user modules in polarized slots to prevent incorrect insertion. The chassis includes an integrated power supply, backplane controller, and operates as either master or slave in distributed system architectures.
