The Advme 1420A is a 32-point high-speed digital I/O VME board. 32-point I/O is divided into four channel each of them is made up of eight points. Each channel has an independent common that allows I/O of digital signals using different power supply modes. This board can be used as an upwardly-compatible replacement for Advme1420.
Isolation:
Photo-coupler isolation is provided between input channels and between input channel and system.
Other features:
Interrupt can be issued to one of the VME interrupt request lines IRQ1 to IRQ7. A switch on the panel can be used to select each of the 8-point channels to be displayed by LEDs.
A device driver for VxWorks® is optionally provided. A sample program is available.
