PCI-1730U

32-channel Isolated Digital I/O Card

Before installation, please make sure that you have 
received the following:

• PCI-1730U card
• Driver CD
• Quick Start User Manual

If anything is missing or damaged, contact your          
distributor or sales representative immediately.

For more detailed information on this product, 
please refer to the PCI-1730U_1733_1734 User 
Manual on the CD-ROM (PDF format).

FCC Class A

This equipment has been tested and found to comply with 
the limits for a Class A digital device, pursuant to part 15 of 
the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference when the 
equipment is operated in a commercial environment. This 
equipment generates, uses, and can radiate radio frequency 
energy and, if not installed and used in accordance with the 
instruction manual, may cause harmful interference to radio 
communications. Operation of this equipment in a residen-
tial area is likely to cause interference in which case the 
user is required to correct interference at his own expense.

CE

This product has passed the CE test for environmental spec-
ifications when shielded cables are used for external wiring. 
We recommend the use of shielded cables. This kind of 
cable is available from Advantech. Please contact your local 
supplier for ordering information.

The Advantech PCI-1730U is a 32-channel isolated 
digital input/output card for the PCI bus. For easy 
monitoring, each isolated digital input channel is 
equipped with one red LED, and each isolated digi-
tal output channel is equipped with one green LED 
to show its ON/OFF status. The PCI-1730U’s iso-
lated digital input channels are ideal for digital input 
in noisy environments or with floating potentials. 
The PCI-1730U provides specific functions for dif-
ferent user requirements.

TTL-level Digital Input/Output

The PCI-1730U has 16 TTL-level digital inputs and 16 
TTL-level digital outputs. The following figure shows 
connections to exchange digital signals with other TTL 
devices:

If you want to receive an 

OPEN/SHORT

 signal from a 

switch or relay, add a pull-up resistor to ensure that the 
input is held at a high level when the contacts are open. 
See the figure below:

Isolated Digital Input

Each of the 16 isolated digital input channels accept 
voltages from 5 to 30 V. Every eight input channels 
share one external common. (Channels 0 ~ 7 use 

ECOM0

. Channels 8 ~ 15 use 

ECOM1

.) The follow-

ing figure shows how to connect an external input 
source to the card's isolated inputs.

Isolated Digital Output

PCI-1730U provides 16 isolated DO channels. If the 
external voltage (5 ~ 40V) is connected to each isolated 
output channel (

IDO

) and its isolated digital output 

turns on (300 mA per channel maximum), the card's 
current will sink from the external voltage. 

CN5 provides two 

EGND

 pins for IDO connection.
