Introduction

The 743X series products are 64-CH high-density isolated digital input
and/or output cards. The 743X series products include the following cards
and are available in different form factors.

The following items are PCI bus products:

• PCI-7432: Isolated 32-CH DI and 32-CH DO card

• PCI-7433: Isolated 64-CH DI card

• PCI-7434: Isolated 64-CH DO card

The following items are 3U CompactPCI products:

• cPCI-7432 : Isolated 32-CH DI and 32-CH DO card

• cPCI-7433 : Isolated 64-CH DI card

• cPCI-7434 : Isolated 64-CH DO card with common ground

configuration

• cPCI-7434P: Isolated 64-CH DO card with common power
configuration

The following items are for 3U CompactPCI with rear I/O:

• cPCI-7432R : Isolated 32-CH DI and 32-CH DO card

• cPCI-7432RP : Isolated 32-CH DI and 32-CH DO card with common

power configuration

• cPCI-7433R : Isolated 64-CH DI card

• cPCI-7434R : Isolated 64-CH DO card with common ground

configuration

• cPCI-7434RP: Isolated 64-CH DO card with common power
configuration

Introduction • 1

The above I/O cards are isolated up-to 5000 Vdc (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 743X series products use PCI -9050 PCI controller to interface the board
to the PCI bus. The PCI-9050 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.
