Curtiss-Wright / ACRA Control KAM/CHS/13U/E/00 13 User-Slot KAM-500 Chassis

The Curtiss-Wright / ACRA Control KAM/CHS/13U/E/00 is a 13-slot chassis purpose-built for the KAM-500 data acquisition system. It combines an integrated power supply module with an 8 MHz x 16-bit digital backplane to create a flexible, modular platform for signal conditioning and data acquisition in aerospace and industrial environments. The chassis accepts up to 13 user-installable modules in any slot combination, with polarized connectors ensuring correct insertion and proper distribution of power, address, data, and control signals.
