Product Details

The XYCOM XVME-103, also known as PN 10103-001, is a discontinued single-height 3U VMEbus RAM/ROM/Flash/EEPROM memory module, designed for legacy XYCOM VME control racks and embedded industrial control systems. It follows IEEE 1014-1987 Rev C1 VMEbus standard and comes with eight 32-pin JEDEC sockets arranged into two independent memory banks, supporting flexible configuration of multiple memory types including RAM, EPROM, Flash and EEPROM. It can reach up to 4MB RAM, 8MB EPROM, 4MB Flash or 4MB EEPROM, and supports 8-bit and 16-bit data transfer as well as read-modify-write cycles for real-time control operations. The onboard battery backup circuit supplies power for CMOS RAM when main power is cut off, preserving critical control parameters, runtime setpoints and application data to avoid data loss after unexpected power interruption. Users can set memory type, base address, access timing and bank selection through on-board jumpers and DIP switches to prevent address conflicts with other VME modules in the same chassis. It communicates with the VME master CPU through standard VME bus cycles, supporting stable read and write operations for control firmware, process recipes and runtime data buffers. The front panel is equipped with LED indicators for power status, bank access activity and low battery warning, which help technicians quickly troubleshoot power failure, battery exhaustion and bus access anomalies during commissioning and routine maintenance. The PCB adopts industrial-grade electronic components and EMC noise suppression design, which can resist electromagnetic interference from inverters and servo drives, as well as vibration, dust and temperature fluctuation in factory environments. This legacy multi-type memory module is mainly supplied as spare replacement and upgrade parts for existing XYCOM VME automation systems. Users need to confirm VME chassis compatibility, memory address mapping and battery health status before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial sites. This model is widely used in CNC control racks, DCS process stations, test measurement platforms and old VME-based automation system retrofit projects.

This vme flash memory module adopts standard 3U single-height VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, memory bank activity and low battery alarm 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 bank and address configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-103 VME memory module is widely applied in legacy VME control racks and industrial automation upgrade projects. It provides flexible multi-format memory expansion and reliable battery-backed data retention for the VME master control system. As a reliable discontinued spare part, the XYCOM XVME-103 retains original VME bus timing and signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
