This unit
The Astronics/EADS/Racal 1260-18 is a VXI C-size high-density switch module featuring 152 SPST channels for signal routing in aerospace, military, and industrial test systems. Each channel handles up to 2 A at 250 VAC or 220 VDC with maximum switching power of 60 W and 125 VA per channel. The module supports message-based and register-based control via VXIbus, user-configurable relay grouping through equate programming lists, and relay coil current monitoring for operational confidence checking. Path resistance remains below 0.5 Ω with thermal EMF under 15 µV, while AC performance into 50 Ω delivers insertion loss below 0.1 dB at 100 kHz rising to 0.7 dB at 10 MHz, crosstalk better than −80 dB at 100 kHz, and isolation exceeding 80 dB at 100 kHz. Open-channel capacitance is capped at 50 pF input-to-ground and output-to-ground, with input-to-output capacitance under 5 pF. The module integrates into standard VXI platforms and accepts a 160-pin mating connector.

Astronics / EADS / Racal 1260-18 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Astronics / EADS / Racal 1260-18. 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 1260-18 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.
