How to Use This Guide
This manual is designed to help you use the PCI-16P16R. The
manual describes how to modify various settings on the PCI-
16P16R card to meet your requirements. It is divided into four
chapters:
lChapter 1, “Introduction”gives an overview of the product
features, applications and specifications.
lChapter 2, “Installation”describes how to install the PCI-
16P16R. The layout of PCI-16P16R is shown, the DIP
switch setting for base Address, jumpers setting for input
signal, and connectors’pin assignment are specified.
lChapter 3, “Low-level Programming”describes the
register structure and how to program the digital inputs and
outputs on the PCI-16P16R.
lChapter 4,”Software User’s Manual”gives you a software
installation guide and describes the API (application
interface) supplied by PCI-16P16R.
lAppendix A, “Relay Contact Protection Circuits”gives
some circuits for relay contact protection.

Chapter 1: Introduction
The PCI-16P16R 16-CH Relay Actuator and Isolated D/I card
is a compact-size and PCI-Bus digital I/O card for IBM
personal computer or compatibles in controlling and sensing
applications.
This card provides 16 relay actuators and 16 opto-isolated
digital inputs. You can use 16 on-board relays to control
power switches or ON/OFF control devices, and use 16 opto-
isolated D/I channels to collect digital inputs in any noisy
environments. It is very essential to use isolated input to
prevent the ground loop problems.
Each relay is matched with one red LED to reflect its ON/OFF
status. Each input channel is jumper selectable to either AC
or DC input control voltage. The isolation voltage is
guaranteed at 1,000V, so that common-mode voltages and
voltage spikes that often occurs in industrial environments
are safety isolated from the PC and the PCI-16P16R.
The digital I/O is via one 37 pins D-type connector that project
through the computer case at the rear of the board.
