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.
1.2 Applications
• Digital signal sensing
• Switch status monitoring
• Limit switch monitoring
• Signal switching
• ON/OFF control
• Valve/solenoid control
• External high-power relay control
• Test automation
1.3 Features
• Works with Advantech TTL DIO cards equipped with 48 D/IO chan-
nels on SCSI 68-pin cable connectors
• 48 opto-Isolated digital input channels
• Detachable screw terminal for easy wiring
• LEDs indicate input logic status
• Inputs buffered with voltage comparators
