This unit
The Astronics/EADS/Racal 1260-37 is a C-Size VXI multiplexer module combining 40 independent Form C (SPDT) relays with eight configurable 1×6 multiplexers in a single slot. This hybrid switching architecture maximizes chassis density for applications requiring both dedicated relay switching and multiplexed signal routing.
Technical Specifications Switching Architecture
40 Form C (SPDT) independent relays
Eight 1×6 multiplexers, user-configurable via on-board jumpers
Signal handling: up to 1 A and 250 VDC or ACrms per channel Multiplexer Configuration The module supports multiple expansion modes: four 1×12 channels, two 1×24 channels, one 1×48 two-wire channel, or one 1×96 one-wire channel. Jumper-selectable configuration allows flexible adaptation to test requirements without hardware replacement. Relay Assurance Relay coil monitoring provides user-selectable confidence checking to verify proper relay operation during test execution. Control Interface Two control options are available: Racal Instruments™ Option 01 (message-based) and Option 01T (message-based and register-based). The 1260-01T Smart Card enables register-based operation with control-register-to-relay mapping. SPDT channels are addressed with a leading "1" (channels 100–139 map to relay positions 00–39). Control Registers operate 8 channels simultaneously with 8 control bits per register; Control Register 0 resides at the module's Base A24 Address.
Key Features
Hybrid SPDT/multiplexer design reduces module count and simplifies interconnection
On-board jumper configuration eliminates firmware dependencies
Relay monitoring ensures switched signal integrity
Dual control interfaces support native and SCPI command sets
C-Size form factor integrates into standard VXI chassis
Typical Applications General-purpose switching and multiplexing in test systems, telecom signal routing, multi-channel data acquisition, and equipment validation requiring both switched and multiplexed signal paths.
Compatibility & Integration Module operates on any VXI platform. Supplied with one set of mating connectors; additional connectors are available in IDC (ribbon cable) or crimp (discrete wire) configurations. The 1260-37 was formerly branded as Racal Instruments and integrates with compatible smart controllers when a 1260-series smart card is installed in the left-most slot of a card set.

Astronics / EADS / Racal 1260-37 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Astronics / EADS / Racal 1260-37. Calibration covers all module-specific parameters per manufacturer datasheet, output accuracy and linearity, frequency accuracy, and VXI register and trigger bus compliance. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Astronics / EADS / Racal 1260-37 faults: relay contact wear, DAC/ADC drift, VXI backplane connector oxidation. Common faults include relay contact wear, DAC or ADC gain drift, and VXI backplane edge connector oxidation. Most modules are repaired at the component level with full post-repair verification in a C-size or D-size mainframe.
