Abaco VME-2170A Digital Output 32-bit optically isolated

VME-2170A Digital Output 32-bit optically isolated

Overview

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
