PCI-bus 64 Channel High Density Isolated Digital Input to Output US$247.00

PCI-bus 64 Channel High Density Isolated Digital Input to Output

The EX-94164 is a 64-channel high-density isolated digital input card isolated up to 5000V DC (excluding cables) for channel-to-computer isolation. It protects your computer against damage caused by accidental contact with high external voltage and eliminates troublesome ground loops.

The EX-94164 fully implements the PCI local bus specification Rev 2.1. All bus relative configurations, such as base memory and interrupt assignment, are automatically controlled by BIOS software.
