Racal Instruments™
1260-115A/B
48/96 Channel Relay Driver
The Racal Instruments™ 1260-115A/B is a 48/96 channel relay driver plug-in
designed for use in VXI Adapt-a-Switch™ carriers (Racal Instruments™ 1260-100
or 1260-101) and the 1256 GPIB/Ethernet Switching System.
Key Features
•t 96 Open-collector driver channels
or 48 high-voltage/current opencollector driver channels
•t Drives up to 50 V and sinks up to
1.5 A per channel
•t Standard Adapt-a-Switch™ plug-in
design for ease of replacement
•t Supports “path-level” switching
Product Information
The 1260-115A has open collector outputs
and provides 96 relay driver channels.
This version can utilize a separate external
pull-up supply of up to 32 VDC for each
independent group. The 1260-115B has
high voltage/current open collector (HVOC)
outputs and provides 48 channels. This
version can utilize a separate external pullup supply of up to 50 VDC.
The Racal Instruments™ Option-01T
interface (for VXI) controls the 1260115A/B using either register-based or
message-based commands. The 1256 (for
GPIB/Ethernet) supports message-based
operations. Refer to the Option-01T/1256
literature for more information about
product specifications and features such
as include, exclude, and scan lists, userdefined path names and reset states.
the system may be defined by name using
the path feature. This makes “path-level”
switching possible for ease of system
configuration and troubleshooting.
The 1260-115A/B plugs easily into a
VXI Adapt-a-Switch™ Carrier or Racal
Instruments 1256 GPIB/Ethernet Switching
System. Please refer to the corresponding
literature for specifications and product
features.
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™.
When the open-collector outputs of the
1260-115A/B are used to control externallymounted switches, all switch paths within
