Safety Precaution - Static Electricity

Follow these simple precautions to protect yourself from harm and the

products from damage.

1. To avoid electrical shock, always disconnect the power from your

PC chassis before you work on it. Don't touch any components on

the CPU card or other cards while the PC is on.

2. Disconnect power before making any configuration changes. The

sudden rush of power as you connect a jumper or install a card may

damage sensitive electronic components.

USB-4761 User Manual 2

Chapter 1 Introduction

Thank you for buying the Advantech’s USB-4761 data acquisition mod-

ule. The Advantech USB-4761 is a powerful data acquisition (DAS)

module for the USB port. It features a unique circuit design and complete

functions for data acquisition and control.

1.1 Features

USB-4761 has the most requested measurement & control functions:

• 8 relay output (Form C) and 8 isolated digital input channels

• LED indicators to show activated relays

• High-voltage isolation on input channels (2,500 VDC)

• High ESD protection (2,000 VDC)

• Wide input range (5 ~ 30 VDC)

• Interrupt handling capability

• Supports USB 2.0

• Bus-powered

• Wiring terminal on Modules

Note: You can install up to sixteen USB-4761’s to a

system because of the restriction of device

BoardID

Note: The power output of an USB port is 500 mA,

while the USB-4761 requires 400mA (Max.). This

means that if an USB hub is used, it will need an

external power supply to support more than one

USB-4761 device.

3 Chapter1

1.1.1 Robust Protection

The USB-4761 digital input channels feature a robust isolation protection

for industrial, lab and machinery automation applications. It durably

withstands voltage up to 2,500 VDC, preventing your host system from

any incidental harms. If connected to an external input source with surge

protection, the USB-4761 can offer up to a maximum of 2,000 VDC ESD

(Electrostatic Discharge) protection.

1.1.2 Wide Input Range

The USB-4761 has a wide range of input voltage from 5 to 30 VDC, and it

is suitable for most industrial applications with 12 and 24 VDC input volt-

age.

1.1.3 Reset Protection for Industrial Applications

When the system has undergone a hot reset (i.e. without turning off the

system power), USB-4761 can either retain outputs values of each chan-

nel, or return to its default configuration as open status, depending on its

onboard jumper setting. This function protects the system from wrong

operations during unexpected system resets.

1.1.4 Plug & Play Function

USB-4761 is a portable Plug-&-Play device that fully complies with the

USB 2.0 specification. During module installation, all bus-related config-

urations such as base I/O address and interrupts are conveniently taken

care of by the Plug-&-Play function. You have virtually no need to set

any jumpers or DIP switches.

Note: For detailed specifications of USB-4761, please

refer to Appendix A, Specifications.

USB-4761 User Manual 4

1.2 Applications

• Industrial On/Off control

• Switch status sensing

• Digital I/O control

• Industrial and lab automation

• SMT/PCB machinery

• Semi-conductor machinery

• PC-based Industrial Machinery

• Testing & Measurement

• Laboratory & Education

• External relay driving

1.3 Installation Guide

Before you install your USB-4761 module, please make sure you have

the following necessary components:

• USB-4761 DAS Module

• USB-4761 User Manual

• Shielded USB 2.0 cable (1.8 m)

• Driver software Advantech DLL drivers (included in the companion

CD-ROM)

• Personal computer or workstation with a USB port (running Windows

2000, or XP)

Some application software is also available for enhanced operation. USB-

4761 works with ActiveDAQ, ActiveDAQ Pro, and other third-party

software packages.

After you have the necessary components and maybe some accessories

for enhanced operation of your USB DAS module, you can then begin the

installation procedure. Figure 1.1 on the next page provides a concise

flow chart to give a broad picture of the software and hardware installa-

tion procedures.
