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

• 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
