2 PCL-734 User's Manual

Introduction

The PCL-734 offers 32 isolated digital output channels on a PC add-

on card. Its isolated output channels provide 1,000 V of protection.

Each I/O channel corresponds to a bit in a PC I/O port. This makes the

PCL-734 very easy to program.

Features

• 32 isolated digital output channels

• High output driving capacity

• High-voltage isolation on isolated output channels (1,000 VDC)

• Open collector outputs (up to 40 VDC)

• D-type connectors for isolated output channels

• High sink current on isolated output channels (200 mA/channel)

• Suppression diode for inductive loads

Applications

• Industrial ON/OFF control

• Contact closure monitoring

• Switch status sensing

• BCD interfacing

• Digital I/O control

• Industrial and lab automation

6 PCL-734 User's Manual

Initial inspection

We carefully inspected the PCL-734 both mechanically and electrical-

ly before shipment. It should be free of marks and in perfect order on

receipt.

As you unpack the PCL-734, check it for signs of shipping damage

(damaged box, scratches, dents, etc.). If it is damaged or fails to meet

specifications, notify our service department or your local sales

representative immediately. Also, call the carrier immediately and

retain the shipping carton and packing material for inspection by the

carrier. We will then make arrangements to repair or replace the unit.

Discharge any static electricity on your body before you touch the

board by touching the back of the system unit (grounded metal).

Remove the PCL-734 card from its protective packaging by grasping

the rear metal panel. Handle the card only by its edges to avoid static

electric discharge which could damage its integrated circuits. Keep the

antistatic package. Whenever you remove the card from the PC, please

store the card in this package for protection.

You should also avoid contact with materials that hold static electricity

such as plastic, vinyl and styrofoam.

Switch and jumper settings

The PCL-734 card has one function switch and three jumper settings.

The following sections tell how to configure the card. You may want

to refer to the opposite page for help identifying card components.

Base address selection (SW1)

You control the PCL-734's operation by writing data to the PC's I/O

(input/output) port addresses. The PCL-734 requires four consecutive

address locations. Switch SW1 sets the card's base (beginning)

address. Valid base addresses range from Hex 200 to Hex 3F0.

However, other devices in your system may be using some of these

addresses.

8 PCL-734 User's Manual

We set the PCL-734 for a base address of Hex 300 at the factory. If

you need to adjust it to some other address range, set switch SW1 as

shown in the following table:
