Product Details

The XYCOM 70202-002 XVME-202 is a discontinued 6U VMEbus digital I/O module built for legacy XYCOM VME control systems and DCS racks. It follows standard VME bus specification and provides isolated digital input and output channels to interface the VME CPU controller with field sensors, solenoid valves, relays, indicator lights and other discrete field devices. The on-board isolation circuit separates the field side and VME bus side, effectively suppressing common-mode noise and transient voltage spikes from field wiring, preventing bus damage caused by ground loop interference. Users can configure channel direction, interrupt trigger conditions and base address via on-board DIP switches and jumpers to match the requirements of different control logic and avoid address conflicts on the shared VME backplane. Each channel is equipped with corresponding status LED indicators on the front panel, which directly show on-off state of input and output signals, helping maintenance staff quickly check signal status, find wiring faults and debug logic programs during commissioning and daily maintenance. This digital I/O board adopts industrial component layout and EMC filtering design, supporting long-term stable operation under vibration, dust and electromagnetic interference in industrial workshops. This legacy module is mainly supplied as spare replacement parts for existing VME automation systems. Users need to confirm channel voltage level, address mapping and interrupt setting before installation. A conformal coated version is optional for high humidity, dusty industrial sites. This model is widely used in chemical process skids, power plant auxiliary control racks, material handling systems and old VME automation renovation projects.

This VME digital I/O card adopts standard 6U VME board structure. It obtains power from the VME backplane. LED indicators display channel status and bus activity 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 address and interrupt configuration backup for fast recovery after hardware replacement.

This XYCOM 70202-002 XVME-202 digital I/O module is widely applied in legacy VME control racks and DCS retrofit projects. It provides stable discrete signal transmission between the VME master controller and field discrete devices. As a reliable discontinued VME spare part, the XYCOM 70202-002 XVME-202 retains original bus timing and channel logic, and effectively reduces the renovation cost of legacy industrial control system maintenance.
