1 Introduction

This manual lists and describes the components of the PCI-723X
family products, which includes:

X PCI-7230: Isolated 16-CH DI and 16-CH DO Card
X PCI-7233: Isolated 32-CH DI Card with COS detection
X PCI-7234: Isolated 32-CH DO Card
X PCI-7234P: Isolated 32-CH DO Card with Source Current

Transistor

X cPCI-7230: Isolated 16-CH DI and 16-CH DO Module for

3U CompactPCI

X LPCI-7230: Isolated 16-CH DI and 16-CH DO Card for low-

profile PCI

X LPCIe-7230: Isolated 16-CH DI and 16-CH DO Card for

low-profile PCI Express

These products have high isolation voltage with either 32 DI or 32
DO channels. The high isolation voltage protects the user’s com­puter against damage caused by accidental contact with high
external voltage and eliminates troublesome ground loops.

The PCI-7230/cPCI-7230/LPCI-7230/LPCIe-7230 provides 16 iso­lated inputs and 16 isolated outputs. The PCI-7230/cPCI-7230 iso­lated I/O channels are isolated to 5000 Vrms, and LPCI/LPCIe­7230 isolated I/O channels are isolated to 2500 Vrms (excluding
cables).

The PCI-7233 provides 32 isolated digital input channels with
COS (change-of-state detection).

The PCI-7234/7234P provides 32 isolated digital output (Darling­ton transistor) channels. The isolation voltage is high up to 5,000
Vrms (excluding cables), both channel-to-channel and channel-to­computer. (PCI-7 234 is sink cu rrent D O card , PCI-7234 P is sour ce
current DO card).

The PCI-7230/7233/7234 use ASIC PCI controller to interface the
board to the PCI bus. The ASIC fully implement the PCI local bus
specification Rev 2.1. All bus relative configurations, such as base
memory address and interrupt assignment, are automatically con­trolled by BIOS software. It does not need any user inter action and

pre-study for the configurations. This removes the burden of
searching for a conflict-free configuration, which can be very time­consuming and difficult with some other bus standards.
