Technical Information

VME / VME64 Backplanes

All WIENER J1, J2 or monolithic J1/J2 VME/VME64 buses are multi-layer backplanes (including power and ground shields) with active automatic daisy chain and active termination outfitted with 96pin DIN connectors as per IEEE-1014-1987 and feature:

  • Strip line technology suitable for data rates of 320Mbyte/s (64bit)
  • High power distribution by current multiplayer / bus bar system
  • Excellent RF shielding
  • Optimized filtering (electrolytic and ceramic filter-capacitors)
  • Minimized ground shift and cross talk
  • Automatic daisy chain
  • flat cable connector for sense and control
  • Provision for up to 8 temperature sensors (module temp. checking)
  • Sense circuit protection by PTC- resistors (Optionally)

Current limits: adjustable to any lower level
Voltage rise characteristics: monotonic 50ms, processor controlled.
Overvoltage protection: crow bar protection trip off adjusted to 125% of nominal voltage each output
DC Off (trip off): within 5ms if >5% deviation from adjusted nominal values,
after overload, overheat, overvoltage, undervoltage (bad status),
