This unit
The Astronics/EADS/Racal 1260-37A is a VXI C-size multiplexer module that integrates 40 Form C (SPDT) switches and eight 1x6 two-wire multiplexers into a single-slot module for test system switching and signal routing. The module supports configurable multiplexer expansion via on-board jumpers - enabling four 1x12, two 1x24, or one 1x48 two-wire channel arrangements - making it adaptable to diverse switching topologies. Signal handling capacity reaches 1A at 250VDC or ACrms, suitable for medium-power switching applications.
Technical Specifications
Switching Elements: 40 independent Form C (SPDT) relays; 8 integrated 1x6 two-wire multiplexers
Multiplexer Configurations: User-selectable via on-board jumpers to four 1x12, two 1x24, or one 1x48 two-wire channels
Signal Capacity: Up to 1A at 250VDC or ACrms
Form Factor: VXI C-size plug-in module, single slot
Connectors: IDC (ribbon cable) or crimp (discrete wire) options
Key Features
Monitored relay coils enable selectable confidence checking for relay operation verification
Compact single-slot design minimizes cabling complexity and reduces chassis footprint
On-board jumper configuration eliminates hardware changes for multiplexer topology reconfiguration
Dual connector options accommodate different wiring infrastructure requirements
Typical Applications
Multi-channel signal routing and analog switching in automated test equipment (ATE)
General-purpose switching networks requiring flexible channel expansion
Confidence-monitored relay control in test systems
Compatibility & Integration The 1260-37A requires installation of a compatible smart controller - either Racal Instruments Option 01 (native command set) or Option 01T (SCPI command set with message-based and register-based operation) - positioned in the leftmost slot of the 1260-xx series module set. This architecture enables standardized VXI platform integration with deterministic message-based control.
