Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its prod-
ucts will be free from defects in materials and workmanship for two years
from the date of purchase.
This warranty does not apply to any products which have been repaired or
altered by persons other than repair personnel authorized by Advantech,
or which have been subject to misuse, abuse, accident or improper instal-
lation. Advantech assumes no liability under the terms of this warranty as
a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous test-
ing, most of our customers never need to use our repair service. If an
Advantech product is defective, it will be repaired or replaced at no
charge during the warranty period. For out-of-warranty repairs, you will
be billed according to the cost of replacement materials, service time and
freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, CPU speed, Advantech products used, other hardware
and software used, etc.) Note anything abnormal and list any
onscreen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your man-
ual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return
merchandize authorization) number from your dealer. This allows
us to process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair and
Replacement Order Card and a photocopy proof of purchase date
(such as your sales receipt) in a shippable container. A product
returned without proof of the purchase date is not eligible for war-
ranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

Chapter 1 Introduction
1.1 General Information
PCLD-8751 and PCLD-8761 are daughter boards that feature 48 isolated
digital I/O channels. PCLD-8751 is equipped with 48 opto-isolated digi-
tal input channels, while PCLD-8761 provides 24 isolated DI and 24
relay channels, which can be used by all Advantech TTL DI/O cards with
a 68-pin SCSI connector, like the PCI-1751 and PCI-1753 series.
In addition to on-board screw terminals for easy wiring, each channel is
equipped with an LED to indicate the status. If the input voltage level is
high or the output channel is activated, the LED will be lit, otherwise the
LED is off. You may configure the channels to work in either positive
logic mode or negative logic mode by setting the on-board jumpers.

Chapter 2 Installation
2.1 Initial Inspection
PCLD-8751 and PCLD-8761 was thoroughly inspected before being
shipped. Before installing the card, make sure that everything has been
included with the package. You should also inspect the card for any
defects or damage that may have occurred during shipment. If you find
anything missing, defective or damaged, contact your dealer immediately.
Here is a list of the materials included with your PCLD-8751 package:
1 x PCLD-8751 48-Channel Isolated Digital Input Board
1 x User Manual
Here is a list of the materials included with your PCLD-8761 package:
1 x PCLD-8761 24-Channel relay output and 24-channel Isolated Digital
Input Board
1 x User Manual
Remove PCLD-8751/PCLD-8761 from its protective packaging. Keep
the packaging, since it may be used to return the card if it needs repairs in
the future. The packaging may also be used if the card is to be stored for
any length of time.
The board should be handled by the edges only. Static electric discharge
can damage the integrated circuits on the board

switches to the “On” position. Following is the mapping table of the DIP
switch and input channels.
JP1: Logic control for input channels.
The input channel control logic is positive when pin1 and pin2 of JP1 are

13 Chapter2
The input and relay control logic can be set separately.
The relay control logic is positive when pin1 and pin2 of JP2 are shorted.
If you short pin2 and pin3 of JP2, the control logic becomes negative.
The factory setting is positive control logic.
JP3: Relay driving power source selection
It is necessary to provide +5 V as the relay channels driving power
source. And the power source can be selected as internal or external by
JP3.
The default setting of JP3 is an internal power source, which means +5V
is provided from the PC. However, you can also select an external power
source by shorting pin2 and pin3 of JP3.
The external power source is provided through TB7. Since there is a
transformer on the circuit, the voltage range of external power should be
within DC +7V ~ +30V.
