1 Introduction

The PCI-7250/7251, cPCI-7252, LPCI-7250 and LPCIe-7250 8CH Relay Output & 8-CH Isolated Digital Input Cards are basic Digital I/O cards for PCI bus compliant computers used in industrial applications.

This PCI-7250/7251 provide 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. The LPCI-7250 and LPCIe-7250 provide 8 relay actuators and 8 optoisolated 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 digital input channels are isolated and suitable applications in noisy environment. For identical non-polarized opto-isolated digita l input channels, switching can be carried out using AC-filtered or non-AC-filtered channels.

PCI-7250 is equipped with LEDs to reflect 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 or a 50-p in SCSI-II connec tor.

Introduction 1

1.1 Features

The PCI-725X Relay Actuator and D/I cards provide the following advanced features:

X 32-bit PCI-Bus, Plug and Play (PCI-7250, LPCI-7250) X 32-bit CompactPCI® Bus, Plug and Play (cPCI-7252) X 8 relay actuator outputs X 8 opto-isolated digital inputs (PCI-7250, LPCI-7250,

LPCIe-7250)

X x1 lane PCI Express Interface (LPCIe-7250) X 16 opto-isolated digital inputs (cPCI-7252) X Onboard LED indicators to show energized relays X Jumper selectable AC-filter/non-AC-filter input signals X On-board relay driving circuits X On-board digital input signal conditioning circuits

Note: PCI-7251 is the extens io n mod u le of th e PCI- 72 5 0. Each

PCI-7251 card provides an additional 8 relay outputs and 8 photo isolated inputs. Up to three PCI-7251 cards can be attached to one PCI-7250 card to provide 32 rela y outputs and 32 photo isolated inputs.

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
