This unit
The Astronics / EADS / Racal 1260-114OC is an open-collector digital I/O plug-in module delivering 96 independently configurable channels for TTL, CMOS, or standard open-collector signal switching. Engineered for the Racal Instruments 1260-100 Adapt-a-Switch VXIbus carrier, this module excels in industrial control, relay switching, and external device interfacing applications requiring voltage-independent output stages.

External pull-up supply (OC version): up to 32 VDC per independent group
External pull-up supply (HVOC version): up to 50 VDC per independent group Control Architecture
2-wire programmable handshaking (active high/low selectable)
Synchronous, asynchronous, and mixed operating modes
Data representation in hex, decimal, or binary formats Physical & Integration
Single-slot, C-size VXIbus form factor
Front-panel installation into 1260-100 Adapt-a-Switch carrier
VXIplug&play framework support (Win32-based)
Driver support: LabWindows/CVI and LabVIEW when used with appropriate controller
Key Features
Channel-by-channel configuration flexibility enables mixed TTL/CMOS/OC operation within a single module
Programmable handshaking eliminates external logic for flow control
High current sinking capability (1.5 A per channel) handles relay coils and solenoid switching directly
Voltage-independent open-collector outputs decouple digital logic from external supply domains
Typical Applications
Industrial relay and solenoid switching matrices
Multi-voltage external device control
Test automation requiring mixed signal-level interfacing
VXI-based test and measurement systems
Compatibility & Integration The module requires the Racal Instruments 1260-100 Adapt-a-Switch carrier and typically an Option-01T Smart Control Module for buffered I/O operations. VXIplug&play software frameworks provide standardized instrument control across Win32 platforms.
