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-7233H: Isolated High-speed 32-CH DI Card with COS
X PCI-7234: Isolated 32-CH DO Card
X PCI-7234P: Isolated 32-CH DO Card (source current)
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 Module for
low profile PCI
These products have high isolation voltage with either 32 DI or 32
DO channels. The high isolation voltage protects the user’s com-
puter against damage caused by accidental contact with high
external voltage and eliminates troublesome ground loops.
The PCI-7230/cPCI-7230//LPCI-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-7230 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 high speed version PCI-
7233H provides 32-CH isolated digital input. The isolation voltage
of PCI-7233H is high up to 2,500 Vrms (excluding cables).
The PCI-7234/7234P provides 32 isolated digital output (Darling-
ton transistor) channels. The isolation voltage is high up to 5,000
Vrms (excluding cables), both channel-to-channel and channel-to-
computer. (PCI-7234 is sink current DO card, PCI-7234P is source
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 con-
trolled by BIOS software. It does not need any user interaction and
pre-study for the configurations. This removes the burden of
