Product Details

The XYCOM PM101229, also known as PMXVME-230, is a discontinued 6U VME bus interface board designed for XYCOM industrial control and VME chassis systems. This board serves as a signal conversion and data transfer interface between the VME backplane bus and field peripheral devices, supporting reliable signal transmission for process control and CNC automation applications. It integrates bus decoding circuits, signal level conversion, surge protection and noise filtering components, which effectively suppress electromagnetic interference from inverters and servo drives on site to avoid data transmission errors during long-time operation. It communicates with the VME master CPU through standard VME bus protocol, realizing bidirectional data exchange, including receiving control commands from the main controller and uploading field feedback signals. Users can adjust on-board DIP switches and jumpers to set base address, interrupt level and bus timing parameters to prevent resource conflicts with other VME modules installed in the same rack. The front edge is equipped with LED indicators for power status, bus access and fault alarm, which helps maintenance technicians quickly diagnose power failure, bus timeout and signal abnormality during commissioning and routine inspection. The PCB adopts industrial-grade electronic components and complete EMC protection design, capable of resisting vibration, dust and temperature fluctuation in machining workshops and chemical process sites. This legacy VME interface board is mainly supplied as spare replacement parts for existing XYCOM VME control systems. Users need to confirm VME chassis compatibility, bus address allocation and host firmware version before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial environments. This model is widely used in CNC control racks, distributed process control stations and old VME-based automation system retrofit projects.

This vme interface board adopts standard 6U VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, bus activity and fault 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 bus address and interrupt configuration backup for fast recovery after hardware replacement.

This XYCOM PM101229 VME interface board is widely applied in legacy VME control racks and industrial automation upgrade projects. It provides stable high-speed bus signal interaction between the master CPU and field peripheral modules. As a reliable discontinued spare part, the XYCOM PM101229 retains original VME bus timing and signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
