Product Details

The XYCOM XVME-260, PN 70260-001, is a discontinued 6U double-width VMEbus relay output module, designed for XYCOM legacy VME control racks and industrial discrete automation systems. This module provides 32 independent magnetic relay output channels, each protected by built-in varistor overvoltage suppression to absorb surge energy when switching inductive loads. Each channel supports 30VDC 1A or 48VAC 0.3A switching capacity, with 300VDC isolation between channels and between each channel and the VME bus side, which effectively blocks ground loop noise and voltage transients from contactors, solenoid valves and motor drives. All relay contacts remain normally open at power-up and reset, offering safe default state for machine interlock and process safety. The module supports software readback of relay status, so the VME host CPU can verify actual switching states and diagnose open or short circuit faults. It operates as a standard VME slave device, supporting byte and word data access cycles. Users can configure base address through on-board DIP switches and jumpers to avoid address conflicts with other VME modules installed in the same chassis. The I/O signals are routed through the P2 connector on the VME backplane. Integrated noise filtering circuits improve stability in harsh factory environments with heavy electromagnetic interference. The front panel is equipped with dedicated LED indicators for each channel, together with power and bus activity LEDs, helping maintenance technicians quickly check relay status, wiring faults and bus communication anomalies during commissioning and routine inspection. The PCB adopts industrial-grade electronic components and reliable EMC protection design, capable of resisting vibration, dust and temperature fluctuation in machining workshops, chemical plants and production line control stations. This legacy relay output 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 load power rating before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial sites. This model is widely used in machine safety interlock, valve control, alarm system activation and old VME discrete control system retrofit projects.

This relay output module adopts standard 6U double-width VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, bus activity and individual channel relay 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 base address configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-260 relay output module is widely applied in legacy VME control racks and industrial automation upgrade projects. It provides isolated high-power switching control for field actuators under the VME master control system. As a reliable discontinued spare part, the XYCOM XVME-260 retains original VME bus timing and signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
