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.

## Technical Specifications

• **Model:** KAM/CHS/06U/E/00 (KAM-500 Series)
• **User Slots:** 6 with polarized connectors

• **Mass (unpopulated):** 1.0–1.4 kg; (fully populated): 1.5–1.9 kg (typical module: 75 g)

## Key Features

• Modular architecture with six user-configurable slots
• Accepts any user module in any slot combination
• Isolated 28V nominal supply with wide input range (18–40 VDC)
• Dual backplane voltage rails for flexible module requirements
• MIL-qualified environmental and EMC performance
• Compact form factor with integral power regulation

## Compatibility & Integration

The KAM/CHS/06U/E/00 integrates into distributed systems as a standalone master or slave node. Polarized module connectors ensure proper insertion. The backplane distributes power, address, data, and control signals to all six user slots simultaneously, enabling parallel module operation.
