Product Details

The XYCOM XVME-135 is a discontinued 6U VMEbus digital I/O module, designed for XYCOM legacy VME control racks and factory automation systems. This digital I/O board provides 32 configurable channels, each channel can be set as digital input or digital output according to field control requirements, supporting 110VDC field signal connection. It serves as the signal interface between the VME master CPU and on-site sensors, limit switches, solenoid valves, relays and other discrete devices, collecting switching status signals and transmitting control commands to field actuators. The board integrates optical isolation circuits, signal conditioning, surge suppression and noise filtering components, which effectively isolate ground loop interference and suppress electromagnetic noise generated by inverters and servo drives, improving the stability of signal transmission in harsh industrial sites. It follows standard VMEbus slave protocol and supports interrupt triggering when the input signal state changes, which helps the host system respond quickly to field events. Users can adjust on-board DIP switches and jumpers to set base address, interrupt level, channel logic mode and input/output direction, avoiding address and interrupt conflicts with other VME modules installed in the same chassis. The front edge is equipped with LED indicators for power status, bus activity and each channel state, allowing maintenance technicians to quickly check signal status, wiring faults and bus communication abnormalities during commissioning and routine inspection. The PCB adopts industrial-grade electronic components and full EMC protection design, capable of resisting vibration, dust and temperature fluctuation in machining workshops and chemical process plants. This legacy digital I/O module is mainly supplied as spare replacement parts for existing XYCOM VME automation systems. Users need to confirm VME chassis compatibility, bus address allocation and field signal voltage before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial environments. This model is widely used in CNC machine tool control racks, material conveying systems, packaging equipment and old VME-based discrete control system retrofit projects.

This vme digital i/o module adopts standard 6U VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, bus activity and channel status 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 channel direction and interrupt configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-135 digital I/O module is widely applied in legacy VME control racks and industrial automation upgrade projects. It provides reliable discrete signal acquisition and output control for the VME master control system. As a reliable discontinued spare part, the XYCOM XVME-135 retains original VME bus timing and signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
