Product Details

The XYCOM XVME-500/4 is a discontinued single-height 3U VMEbus analog input module, designed for XYCOM legacy VME control racks and industrial high-density analog data acquisition systems. This module supports flexible channel configuration, providing up to 32 single-ended analog input channels or 16 differential input channels for capturing continuous analog signals from field transmitters, pressure sensors, temperature transducers and flow meters. It adopts 12-bit high precision A/D conversion architecture, delivering stable conversion results for unipolar 0–10V and bipolar ±5V, ±10V input ranges, with typical input impedance of 100kΩ for single-ended channels. The module supports high-speed sequential scanning of channels, and it can generate hardware interrupts to notify the VME master CPU once conversion cycles are finished, which helps the host controller obtain real-time process readings without frequent polling.

This analog acquisition board follows IEEE 1014 VMEbus specification and works as a VME slave device. Users can configure base address, interrupt vector and scan sequence parameters through on-board jumpers and DIP switches to avoid address and interrupt conflicts with other VME modules installed in the same chassis. The signal conditioning circuit integrates low-pass filtering and transient suppression components, effectively filtering electromagnetic noise generated by inverters and servo drives, and improving measurement stability in electrically noisy factory environments. It can also cooperate with 3B series signal conditioning modules to expand compatibility for current signals, thermocouple and RTD sensors, greatly expanding the application coverage of the data acquisition module.

The front panel is equipped with LED indicators for power status and bus activity, helping maintenance technicians quickly judge module power supply status, bus communication faults and configuration errors 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, power stations and automated test benches. This legacy analog input 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 signal wiring definition before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial sites. This model is widely used in process variable monitoring, industrial test equipment, environmental data logging and old VME analog acquisition system retrofit projects.

This analog input module adopts standard 3U single-height VME rack mount structure. It draws power from the VME backplane. LED indicators display power status and bus activity for convenient on-site inspection. The operating temperature range is -40°C to +80°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 scan sequence and interrupt configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-500/4 analog input module is widely applied in legacy VME control racks and industrial automation upgrade projects. It provides high-density multi-channel analog signal acquisition and 12-bit conversion for the VME master control system. As a reliable discontinued spare part, the XYCOM XVME-500/4 retains original VME bus timing and signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
