The Advme1209A is a 64-point Digital input board. Input is divided between eight input channels with a common for every eight points using different power supplies.
Photo-coupler isolation
Photo-coupler isolation is provided between input channels and between input channel and the VME bus. High speed photo-coupler supports fast input.
Other features:
Interrupt can be issued to one of the VME interrupt request lines from *IRQ1 to *IRQ7.
A switch on the front panel allows to select each group of 8 inputs in order to display them by LEDs.
A device driver for VxWorks and a sample program are optionally available.
