DESCRIPTION:

PCI-7251 is an 8 Relay and 8 Isolated Digital Inputs extension board for PCI-7250. The functions of PCI-7251 are the same as PCI-7250. The PCI-7251 misses some circuitry and therefore it has be connected with PCI-7250 to function. All bus interfacing is controlled by PCI-7250. Up to 3 PCI-7251's can be connected to one PCI-7250. Adding modules will extend the PCI-7250's DIO capability from 8 Di & DO to 16, 24 or 32 DI & DO. Because PCI supports a 32-bit bus, 32 digital inputs or 32 digital outputs can be accessed with a single instruction.
