AVME9440:
Digital I/O, Isolated (16 inputs and 16 outputs)
• 16 input and/or 16 outputs (32 channels)
• Isolated (channel-to-channel) I/O
These boards provide an economical method for isolating and interfacing digital I/O signals to the VMEbus. Built-in optical relays eliminate the expense of external relay panels and simplify installations. The outputs can control valves, switch counters, mechanical/optical relays, indicator lamps and more.
On-board relays isolate all inputs and outputs from each other and from the VMEbus for protection against transients from ground loops and pick-up.
Selectable input threshold voltages let the user adapt the input points to a variety of applications including contact closures, alarm trips, switches, and power supply on/off monitoring.
Debounce circuitry offers a selectable time delay to eliminate false signals resulting from contact bounce commonly experienced with mechanical relays and switches.
