VME-2170A Digital Output

32-bit optically isolated

VME-2170A Digital Output


The VME-2170A optically coupled digital output board consists of VMEbus compatibility logic,data control logic, four 8-bit output registers, and 32 optically isolated high-level outputs. The board is implemented as a double Eurocard form factor PC board, and provides all necessary address decoding and data transfer control logic to accept both 8- and 16-bit data transfers. Optical couplers isolate the 32 outputs from each other and from the VMEbus. Both supervisory and nonprivileged data transfers are supported.

  • On-board DIP switches provide 14-bit board address selection
  • Double Eurocard format with front panel
  • 8- or 16-bit data transfers
  • High isolated potential; 1 kV sustained, 6 kV pulsed
  • Positive or negative true options
  • High output voltage tolerance to 30 V normal mode
  • Open collector style output
  • Current source or sink output capability with low current option
  • Field configurable pull-up resistors
  • Externally supplied pull-up voltage for maximum isolation
  • 2.5 or 300 mA outputs
  • 32 optically isolated outputs
