1260-1114
PXI/cPCI High-Density, Digital I/O Card
The Racal Instruments™ 1260-1114 is an innovative, seamless integration of an
off-the-shelf Adapt-a-Switch™ PXI digital I/O card on a Racal Instruments™ PXI
carrier. The module installs in any PXI/cPCI chassis without the need for user
supplied software or hardware to install or operate.
Key Features
•t Adapt-A-Switch® high-density
digital I/O module on a Racal
Instruments PXI carrier
•t Extended depth (12.1”) for highdensity and market-leading
performance
•t Available 96 TTL/CMOS channels;
48 HVOC channels
•t Unmatched 8 MHz data transfer
speed
Product Information
The 12.1” 1260-1114 module length utilizes
the available service area between the
front of a chassis and a cable/connector
receiver.
It has 85% greater component density than
a typical PXI digital I/O module, providing
higher digital I/O performance. Its high input
data rate of 200 kHz exceeds typical digital
I/O slow speed data rates. Also, its 1.5 A
input current (HVOC) far exceeds typical
150 mA ratings in the market today.
To meet the many customer digital I/O
needs, the module is available in TTL,
CMOS, OC (standard open collector) or
HVOC (high-voltage/current open collector)
I/O channels.
Each TTL or CMOS I/O channel may
be placed in high-impedance, tri-state
mode. Additionally, the CMOS version
features TTL level compliance provided
the maximum current of the driver is not
exceeded (refer to the specifications).
The HVOC module is available in a highvoltage/high-current, 48-channel, OpenCollector (OC) version. The OC version can
utilize a separate, external, pull-up supply
for up to 32 VDC for each independent
group, and the HVOC version can utilize
a separate, external, pull-up supply for
up to 50 VDC. These versions are ideal
for controlling external digital circuitry,
switches, relays, and similar devices.
For ease of use, and greater programming
flexibility, the I/O channels are grouped into
12 separate groups with 8 channels each.
Each channel can be configured as an
input or output and individually controlled in
asynchronous mode or with other channels
in synchronous mode.
With a high 960-channel count, each 12601114 can address a significant portion of all
the required digital I/O’s to be captured in
a single PXI chassis slot. The module has
a 2-wire handshake mode available for the
control of synchronous I/O transactions.
Each handshake line can be programmed
as either active high or active low, providing
a flexible interface with user signals.
The 1260-1114 is programmable in several
operating modes and data may be manipulated in hex, decimal, or binary.
In keeping with cPCI requirements, the
module can be ordered either as a 5 V
or 3.3 V PXI bus module. The module
includes drivers for LabWindows™/CVI
5.1 and LabVIEW™ 7.0.
The 1260-1114 has 8 MHz data transfer
speed for fast data transfer that is required
for timely, uninterrupted data acquisition
and processing.
