Product Details

The XYCOM 70113-001 XVME-113 is a discontinued 6U VMEbus memory expansion module, designed for legacy XYCOM VME embedded control systems and DCS racks. This memory board supports configurable RAM and ROM storage, which can store control firmware, application logic, lookup tables and real-time process data buffer for VME CPU master boards. It follows standard VME bus protocol and supports VME A16/A24 address space. Users can set the base address and memory partition via on-board DIP switches and jumpers, avoiding address conflicts when multiple VME cards are installed in the same backplane. The ROM area can retain program data after power loss, while the RAM section offers high-speed read-write access for dynamic process variables. The circuit adopts industrial-grade EMC protection and noise filtering design, suitable for continuous operation under vibration, dust and electromagnetic interference in factory environments. The front panel is equipped with LED status indicators for power supply and bus access activity, helping maintenance technicians quickly check working status and diagnose bus faults, address setting errors or hardware failures during commissioning and routine inspection. This legacy memory module is mainly supplied as spare replacement parts for existing VME automation control systems. Users need to confirm memory capacity, address mapping range and bus timing compatibility 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 racks, material handling control systems 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 70113-001 XVME-113 memory module is widely applied in legacy VME control racks and DCS system upgrade projects. It provides reliable program storage and high-speed data caching for VME host controllers. As a reliable discontinued VME spare part, the XYCOM 70113-001 XVME-113 retains original bus timing and memory mapping logic, and effectively reduces the renovation cost of legacy industrial control system maintenance.
