Astronics / C&H Technologies VX402C-64 Active Module Carrier

The Astronics / C&H Technologies VX402C-64 Active Module Carrier adapts VME, VME64, or VXI (A or B size) modules for integration into C-size VXI mainframe chassis. The carrier delivers an actively buffered electrical interface for standard bus signals, ensuring full compliance with VME/VXIbus driving and loading specifications. It supports legacy system upgrades and provides flexible power conditioning options for VME64 modules. ## Technical Specifications Bus Compliance • VXIbus Specification Revision 1.4 (single-slot C-size modules) • VMEbus Specification ANSI/IEEE STD 1014-1987, IEC 821, IEC 822 Address & Data • Addressing: A32/A24/A16 • Data transfers: D32/D16 Slave • Interrupt and trigger support: Yes Electrical Interface • Active logic buffering for data, address, interrupt, and trigger lines • ECL and TTL buffered outputs • Compliant with VME/VXIbus driving and loading specifications • Pass-through P2 connectors for VME module integration Power Supply Options VME64 power supplied from VXI backplane or via power converters: • Option -0001: 37 W combined; +3.3 V from VXI +5 V • Option -0002: 40 W combined; no +3.3 V supply • Option -0003: 40 W combined; 23 W +3.3 V from VXI -24 V • Option -0004: 40 W combined; 23 W +3.3 V from VXI +24 V • Option -0005: 63 W combined; +5 V from VXI +24 V, +3.3 V from VXI -24 V All power limited to maximum 1.2 A per VXI power pin.
