Product Details

The XYCOM XVME-530, PN 70530-001, is a discontinued 6U VMEbus isolated analog output module, built for XYCOM legacy VME control racks and closed-loop industrial process control systems. It provides 8 independent analog output channels with 12-bit DAC resolution, and every channel can be individually configured via jumpers for multiple voltage or current ranges, including 0-5V, 0-10V, ±2.5V, ±5V, ±10V and 4-20mA current loop. Each channel features 300V optical isolation between the VME logic side and the field wiring, which effectively cuts off ground loop noise and suppresses common-mode interference, protecting the host bus from voltage transients generated by inverters, servo drives and contactors. The module delivers a total error of ±0.5 LSB, with guaranteed monotonicity and stable settling performance for accurate setpoint regulation. The conversion time is 42 microseconds per channel, supporting fast analog updates for dynamic control loops.

This isolated dac board works as a standard VME slave device following IEEE 1014 VMEbus specification. Users can set base address and output mode through on-board DIP switches and jumpers to avoid address conflicts with other VME modules in the same chassis. It receives digital values from the VME master CPU and converts these digital commands into continuous analog signals to drive valve positioners, variable frequency drives, proportional actuators and other field control devices. Built-in low-pass filtering and surge suppression circuits keep the output signal steady in electrically noisy factory environments. The module supports status readback for diagnostic checks, helping engineers verify output integrity during commissioning and routine maintenance.

The front panel is equipped with LED indicators for power status and bus activity, allowing maintenance technicians to quickly diagnose power faults, bus communication failures and configuration errors. The PCB adopts industrial-grade electronic components and reliable EMC protection design, capable of resisting vibration, dust and temperature fluctuation in chemical plants, power stations, water treatment systems and automated test benches. This legacy isolated analog 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 wiring definition before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial sites. This model is widely used in flow and pressure closed-loop regulation, analog signal simulation, actuator control and old VME analog control system retrofit projects.

This isolated analog output module adopts standard 6U 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 0°C to 65°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 and channel range configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-530 analog output module is widely applied in legacy VME control racks and industrial automation upgrade projects. It provides multi-range isolated voltage and current control signals for the VME master control system. As a reliable discontinued spare part, the XYCOM XVME-530 retains original VME bus timing and analog signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
