1.1 Introduction

The PCL-812PG is a high performance, high speed, multi-function

data acquisition card for IBM PC/XT/AT and compatible

computers. The high-end specifications fo this full-sized card, and

complete software support from third-party vendors makes it ideal

for a wide range of applications in industrial and laboratory

environments. These applications include data acquisition, process

control, automatic testing and factory automation.

1.2 Key Features

• 16 single-ended analog input channels

• An industrial standard 12-bit successive approximation converter

(HADC574Z) to convert analog inputs. The maximum A/D

sampling rate is 30 KHz in DMA mode.

• Software programmable analog input ranges.

• Bipolar: +/- 5V, +/- 2.5 V, +/- 1.25V +/- 0.625 V +/- 0.3125 V

• Three A/D trigger modes:

• Software trigger

• Programmable pacer trigger

• External pulse trigger

• The ability to transfer A/D converted data by program control,

interrupt handler routine or DMA transfer.

• An Intel 8253-5 Programmable Timer/Counter provides pacer

output (trigger pulse) at the rate of 0.5 MHz to 35 minutes/pulse.

The timer increment is 2 MHz. One 16-bit counter channel is

reserved for user configuration applications.

• Two 12-bit monolithic multiplying D/A output channels. An

output range from 0 to +5V or 0 to +10V can be created by using

the on-board -5V or -10V reference. This precision reference is

derived from the A/D converter reference. External AC or DC

references can also be used to generate other D/A output ranges.

• 16 TTL/DTL compatible digital inputs, and 16 digital output

channels.

1.3 Expansion Capabilities

To complement the powerful features of the PCL-812PG, the

versatility of the card can be enhanced by using the following

optional daughter boards:

PCLD-789 Amplifier/Multiplier Board

This powerful front end analog input signal conditioning card can

multiplex 16 differential inputs to one A/D input channel. A high

grade instrumentation amplifier provides switch selectible gains of

0.5, 1, 2, 10, 50, 100, 200, 1000 or any user-definable gain.

PCLD-787 Eight Channel Simultaneous Sample and Hold

Front-End Board

The board allows up to eight analog inputs to be acquired

simultaneously with less than 30 ns of channel-to-channel sample

time uncertainty.

PCLD-786 AC/DC Power SSR and Relay Driver Board

This board provides 8 channels of photo-couple isolated solid-state

relay modules, plus an additonal 8 external relay driver outputs.

PCLD-785/885 Relay Output Board

This board provides 16 SPDT relays driven by the 16-bit digital

output channels of the PCL-812PG.

PCLD-782 Isolated D/I Board

This 16-channel opto-isolated digital input board provides an easy

way to input digital signals to the PCL-812PG.

PCLD-780 Wiring Terminal

Wiring terminal board for easy analog and/or digital I/O

connections

PCLD-779 Eight Channel Isolated Multiplexer and

Amplifier Board

Offers multi-channel temperature measurements when connected

with a PC-LabCard.

PCLD-770/7701/7702 Signal Conditioning Modules

PCLD-770 Signal Conditioning Module Carrier Board.

With the PCLD-770 board, you can configure your requirements

with a signal conditioning module such as the PCLD-7701 or

PCLD-7702.

PCLD-7701 Isolated Amplifier

PCLD-7702 Amplifier with I/V Source

PCLD-5B16 Module Carrier Board

This module carrier board is equipped with 16 channels of 5B

series input and/or output modules which provide a complete

solution for signal conditioning applications.

1.4 Software Support

The PCL-812PG also provides powerful and easy to use software

driver functions which can be accessed by referring a user-defined

parameter table. These driver functions simplify programming,

especially when you want to use some of the sophisticated features

available with the PCL-812PG, for example, interrupt or DMA

data transfer.

To provide PCL-812PG users with more application support, a

variety of excellent third-party application software packages have

been integrated with the PCL-812PG. At present, the PCL-812PG

is supported by the following software:

PC-LabsDAS

Turnkey, menu-driven, general purpose data acquisition package

from Advantech

Labtech Notebook, PC-Scope, PC-Streamer, SNAPSHOT,

etc.

A complete software product catalog is available free from your

local PC-LabCard representative.
