PCI-7230
Isolated 16 Digital Inputs & 16 Digital Outputs

Introduction

The PCI-7230 provides 32 isolated digital I/O, 16 Isolated inputs and 16 isolated outputs. The isolated I/O channels are
isolated to 2,500 Vrms (excluding cables), both channel-to-channel and channel-to-computer. It protects your computer
against damage caused by accidental contact with high external voltage and elimates troublesome ground loops.

The PCI-7230 uses SAIC PCI controller to interface the board to the PCI bus. The ASIC fully implement the PCI
local bus specification Rev 2.0. All bus relative configurations, such as base memory address and interrupt assignment, are
automatically controlled by BIOS software. It does not need any user interaction and pre-study for the configurations.
This removes the burden of searching for a conflict-free configuration, which can be very time consuming and
difficult with some other bus standards.

The advanced features of the PCI-7230 are

• 16 Isolated Digital Input Channels
• 16 Isolated Digital Output Channels
• High output driving capability
• 2,500 Vrms high voltage isolation
• Interrupt is controlled from external signal
• Dual interrupt trigger
• 200mA sink current on isolated output channles
• Up to 24V voltage protection for isolated input
• 37-pin D-type connector
