Product Details

The XYCOM 70100-001 XVME-101 is a discontinued VMEbus memory expansion module designed for XYCOM legacy VME control systems, widely used in industrial process control and DCS platforms. It is built as a standard 6U VME form factor card and directly plugs into the VME backplane to expand high-speed memory space for the host VME CPU board. This module supports mixed installation of RAM, EPROM and EEPROM chips, providing flexible storage for control firmware, application programs and real-time process data cache. Users can configure base address via on-board DIP switches and jumpers to avoid address conflicts when multiple VME cards run on the same backplane. The memory module supports stable data access under VME bus protocol, and the EEPROM area can retain key configuration parameters after power failure, which is critical for uninterrupted process control. The circuit adopts industrial-grade design with noise suppression and EMC protection to resist vibration and electromagnetic interference in factory environments. Front panel LED indicators show power status and bus access activity, which helps technicians quickly diagnose hardware faults and bus communication issues during commissioning and routine maintenance. This legacy memory card is mainly supplied as spare replacement parts for existing XYCOM VME automation systems. Users need to confirm chip type, memory capacity and VME address mapping before installation. A conformal coated version is optional for high humidity, dusty industrial sites. This model is widely used in chemical process skids, power plant DCS control systems, material handling control racks and old VME-based automation renovation projects.

This VME memory expansion card adopts standard 6U VME board structure. It draws 5VDC power supply from VME backplane. LED indicators display power status and bus activity for convenient on-site inspection. The operating temperature range is 0°C to 50°C, storage temperature ranges from -40°C to 85°C, relative humidity 5% to 95% non-condensing. It complies with industrial shock, vibration and EMC standards and has CE certifications. It supports memory address configuration backup for fast recovery after hardware replacement.

This XYCOM 70100-001 XVME-101 memory module is widely applied in legacy VME control racks and DCS system upgrade projects. It provides reliable program storage and high-speed data buffer for VME host controllers. As a reliable discontinued VME spare part, the XYCOM 70100-001 XVME-101 retains original bus timing and memory mapping logic, and effectively reduces the renovation cost of legacy industrial control system maintenance.
