1260-114
High-Density Digital I/O Plug-in
The Racal Instruments™ 1260-114 is a 96-channel digital I/O plug-in for the
Adapt-a-Switch™ platform. A 48-channel high voltage/current open-collector
version is also available. The 1260-114 installs easily and directly from the front
panel into the Racal Instruments™1260-100 Adapt-a-Switch™ VXIbus carrier.
Please refer to the 1260-100 data sheet for specifications and product features.
Product Information
Key Features

design for ease of replacement
The 1260-114 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 a high-impedance, tristate mode. Additionally, the CMOS version
features TTL level compliance, provided
the maximum current of the driver is not
exceeded (refer to the specifications).
The high channel count of the digital I/O
plug-ins allows a significant portion of
digital I/O to be realized in a single slot
of the Adapt-a-Switch™ carrier, saving
valuable VXIbus chassis space. The 1260114 provides 96 digital I/O channels in
twelve groups of eight bits each.
The 1260-114OC version can utilize a
separate external pull-up supply for up
to 32 VDC for each independent group,
and the 1260-114 HVOC can utilize
a separate external pull-up supply for
up to 50 VDC. The versions are ideal
for controlling external digital circuitry,
switches, relays and similar devices. Each
channel is configurable as an input or an
output and can be individually controlled in
asynchronous mode or with other channels
in synchronous mode.
The 1260-114 has a two-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 1260-114 is programmable in
several operating modes and data may
be manipulated in either hex, decimal or
binary. Memory is available on the Racal
Instruments™ Option-01T switch system
controller to allow buffered I/O operations.
The Adapt-a-Switch™ series includes
VXIplug&play support for frameworks
based on Microsoft Win32® application
programming interface, including drivers
for LabWindows™/CVI and LabVIEW™.
Please refer to the Option 01T data sheet
for additional product features.
