Product Details

The XYCOM 70505-001 XVME-505/1 is a discontinued 6U VMEbus analog output module, belonging to the XVME-505 series and developed for legacy XYCOM VME control racks and DCS process automation systems. This analog output board provides 4 independent analog output channels, which can be configured to support standard industrial signal ranges including 0-10V voltage and 4-20mA current signals. It adopts high-precision D/A conversion chips to ensure stable and accurate analog output, which is used to drive control equipment such as control valves, variable frequency drives, positioners and signal indicators in the field. The module follows standard VME slave interface and supports A16 and A24 address space. Users can set the base address and output range configuration through on-board DIP switches and jumpers to avoid address conflicts on the shared VME backplane. Each channel is equipped with overvoltage and short-circuit protection circuits to prevent damage caused by field wiring faults. The front panel is equipped with LED status indicators for power supply and channel working status, which helps maintenance technicians quickly check working status, locate wiring faults and verify output signal parameters during commissioning and daily inspection. The circuit design adds EMC filtering and noise suppression components, which can resist electromagnetic interference and mechanical vibration in chemical, power and oil & gas workshop environments, ensuring long-term stable closed-loop regulation. This legacy analog output module is mainly supplied as spare replacement parts for the maintenance and renovation of existing VME automation systems. Users need to confirm the signal type, load impedance and address mapping parameters before installation. A conformal coated version is optional for high humidity, dusty industrial sites. This model is widely used in chemical process skids, boiler regulation control, oil & gas flow control loops and old VME-based DCS upgrade projects.

This VME analog output card adopts standard 6U single-slot VME board structure. It draws 5VDC power supply from VME backplane. LED indicators display power status 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 output range and address configuration backup for fast recovery after hardware replacement.

This XYCOM 70505-001 XVME-505/1 analog output module is widely applied in legacy VME control racks and closed-loop process control retrofit projects. It provides reliable analog control signals for VME host controllers to adjust field process variables. As a reliable discontinued VME spare part, the XYCOM 70505-001 XVME-505/1 retains original bus timing and conversion logic, and effectively reduces the renovation cost of legacy industrial control system maintenance.
