PCIE-1750U/UH User Manual 2
1.1 Introduction
The PCIE-1750U/UH is a series of 32-ch digital input/output card with PCI Express
interface.
The key feature this series provides is selectable NPN/PNP direction on digital out-
put function. Users can select the direction according to their needs, setting by soft-
ware APIs.
The digital filter PCIE-1750UH provides on every single channel is ideal for acquiring
digital signals in noisy environments. On the other hand, the interrupt function pro-
vided on each channel gives not only a way monitoring the DI status instead of soft-
ware polling to save computing resources, but also a better real-time performance.
The following sections will describe further information about features and installa-
tion, along with some brief instruction on software and accessories for the PCIE-
1750U/UH card.
1.2 Features
PCIE-1750U/UH
 16-ch isolated digital input
 16-ch isolated digital output with software configurable both PNP (source)/ NPN
(sink) type
 High output driving capacity
 Interrupt handling capability for all DI channels (PCIE-1750UH only)
 Selectable digital filter time for all DI channels (PCIE-1750UH only)
 High isolation voltage (2,500 VDC)
The Advantech PCIE-1750U/UH offers the following main features:
Robust Protection
The PCIE-1750U/UH digital input channels feature robust isolation protection for
industrial, lab and machinery automation applications. It durably withstands voltage
up to 2,500 V
DC
, preventing your host system from any incidental harm. If connected
to an external input source with surge-protection, the PCIE-1750U/UH can offer up to
a maximum of 2,000 V
DC
ESD (Electrostatic Discharge) protection. Even with an
input voltage rising up to 70 V
DC
, the PCIE-1750U/UH can still manage to work prop-
erly, albeit only for a short period of time.
Wide Input Range
The PCIE-1750U/UH has a wide range of input voltage from 10 to 30 V
DC
, and is
suitable for most industrial applications of 12 V
DC
or 24 V
DC
input voltage.
Plug-and-Play Function
The PCIE-1750U/UH is a Plug-and-Play device, which fully complies with PCI
Express Specification Rev V1.0. During card installation, there is no need to set
jumpers or DIP switches. Instead, all bus-related configurations such as base I/O
address and interrupt are automatically done by the Plug-and-Play function.
