1.1

Overview

This  chapter  provides  an  overview  of Advantech  industrial  data  acquisition  (iDAQ)

modules for iDAQ-815, ranging the product lineups, features and accessories.
iDAQ-815  is  an 8-channel  RTD  input  module.  It  features  24-bit  resolution,  400S/s

sampling rate, and supporting most of popular RTD materials. It's suitable for RTD

measurement with high accuracy requirements.

Product Features

1.3.1

Power Input

The power input of all the iDAQ I/O modules come from iDAQ chassis via the DB 15-

pin connector. The iDAQ I/O modules are powered on when the power of iDAQ chas

-

sis is connected.

1.3.2

BoardID

A board ID (BID) can be assigned to the iDAQ chassis by the rotary switch and slot

number. The board ID will be shown in the software and can be used to distinguish

modules. The number shown around the rotary switch is in hexadecimal format. For

example, “A” represents 10 in decimal format, and “F” represents 15 in decimal for

-

mat. The number assigned to each iDAQ module follows a rule combining the Chas

-

sisID and slot number. Refer to section 3.4 for detailed information.

1.3.3

Plug and Play Device

The iDAQ modules are hot-swappable in the iDAQ chassis. The modules will be rec

-

ognized instantly in the software (Installed Devices list) when they are plugged into

the iDAQ slots and they can be removed as soon as they are disabled in the soft

-

ware. Therefore, it’s strongly recommended to operate these actions whilst the sys

-

tem is in idle mode not data acquisition mode.
