1 Introduction
The PCI-7250/7251 and cPCI-7252 Relay Actuator and Isolated
D/I cards are basic Digital I/O cards for PCI bus compliant computers used in industrial applications.
This PCI-7250 and PCI-7251 provides 8 relay actuators and 8
opto-isolated digital inputs. Of the eight relays, four are Form C
(R0~R3) and four are Form A (R4~R7). The cPCI-7252 provides 8
relay actuators and 16 opto-isolated digital inputs; all relays are
Form C. They are very suited for constant ON/OFF control
devices. For convenience the above models will be referred to as
PCI-725X in this manual.
All channels are isolated and suitable for collecting digital input
signals in a noisy environment. For identical non-polarized optoisolated digital input channels, switching can be carried out using
AC-filtered or non-AC-filtered channels.
A LED reflects the status of each relay output. When a relay is
energized, its corresponding LED will turn ON, otherwise it is OFF.
The relay outputs and digital inputs are controlled by two bytes of
I/O addresses. When a bit is read or written, its output status will
be controlled, or its input status will be monitored. The I/O signals
are routed through to a 37-pin D-type connector that protrudes
through the computer case at the rear.
Introduction 1
1.1 Features
The PCI-725X Relay Actuator and D/I card provides the following
advanced features:
X 32-bit PCI-Bus, Plug and Play (PCI-7250)
X 32-bit CompactPCI® Bus, Plug and Play (cPCI-7252)
X 8 relay actuator outputs
X 8 opto-isolated digital inputs (PCI-7250)
X 16 opto-isolated digital inputs (cPCI-7252)

X On-board digital input signal conditioning circuits
Note: The PCI-7251 attaches to a PCI-7250 card. Each PCI-7251
card provides an additional 8 relay output and 8 photo isolated input signals. Up to three PCI-7251 cards can be attached
to one PCI-7250 card to provide 32 relay output signals and
32 photo isolated inputs signals.
1.2 Applications
X Industrial ON/OFF control
X External high power relay driving signal switching
X Laboratory automation
X Industrial automation
X Switch contact status sensing, limit switch monitoring,
X Useful with A/D and D/A cards to implement a data acquisi-
tion & control system

1.4 Software Support
ADLINK provides versatile software drivers and packages to
address different approaches to building a system. We not only
provide programming libraries such as DLLs for many Windows
systems, but also provide drivers for many software packages
such as LabVIEW®, HP VEETM, DASYLabTM, InTouchTM,
InControlTM, ISaGRAFTM, etc.
All software options are included in the ADLINK CD. Non-free software drivers are protected with licensing codes. Without the software code, you can install and run the demo version for two hours
for trial/demonstration purposes. Please contact ADLINK dealers
to purchase a formal license.
Programming Library
For customers who are writing their own programs, we provide
function libraries for many different operating systems, including:
X DOS Library: For Borland C/C++, and Microsoft C++, the
functions descriptions are included in this user’s guide.
X Windows 95 DLL: For VB, VC++, Delphi, BC5, the functions
descriptions are included in this user’s guide.
X PCIS-DASK: Included device drivers and DLL for Windows
98, Windows NT and Windows 2000. A DLL is a binary
compatible across Windows 98, Windows NT and Windows
2000. That means all applications developed with PCISDASK are compatible across Windows 98, Windows NT,
and Windows 2000. The developing environment can be
VB, VC++, Delphi, BC5, or any Windows programming language that allows calls to a DLL. The user’s guide and function reference manual of PCIS-DASK are in the CD. Please
