Product Details

The XYCOM XVME-230, PN 74230-001, is a discontinued 6U VMEbus intelligent counter module, designed for XYCOM legacy VME control racks and precision motion measurement systems. This intelligent counter module can operate autonomously after receiving setup commands from the VME host CPU, supporting multiple measurement and control functions including event counting, position detection, frequency measurement, period measurement, pulse width capture and stepper motor control. It can process input signals up to 5MHz, delivering high resolution readings for pulse and quadrature signals from encoders, proximity sensors and pulse generators. The board supports simultaneous multi-function operation, and it can generate programmable output pulses, fixed frequency signals and periodic interrupts to trigger synchronized actions in the control system. The module works as a VME slave and uses XYCOM interprocessor communication protocol to exchange data with the main processor. Users can configure base address, interrupt vector, counting mode and output waveform parameters via on-board jumpers and DIP switches to avoid resource conflicts with other VME modules in the same rack. Signal conditioning and noise suppression circuits are integrated to filter electromagnetic interference from inverters and servo drives, ensuring stable sampling accuracy in noisy industrial environments. The front panel is equipped with LED indicators for power status, bus access and channel activity, helping maintenance technicians quickly locate wiring faults, signal loss 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 and test measurement stations. This legacy intelligent counter 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 pulse signal wiring requirements before installation. A conformal coated version is optional for high humidity, dusty industrial sites. This model is widely used in CNC axis positioning, stepper motor drive control, speed monitoring and old VME motion measurement retrofit projects.

This intelligent counter module adopts standard 6U VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, bus activity and channel signal 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 counting mode and interrupt configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-230 intelligent counter module is widely applied in legacy VME control racks and industrial motion control upgrade projects. It provides autonomous high-precision pulse measurement and motion signal generation for the VME master control system. As a reliable discontinued spare part, the XYCOM XVME-230 retains original VME bus timing and communication compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
