This unit
The Interface Technology IO110VXI is a 128-channel CMOS digital I/O module designed for high-density signal interfacing in industrial and automation applications. It delivers simultaneous read/write capability across all 128 channels, software-configurable I/O groups, and multiple logic format support including CMOS, TTL, TTL Open Collector, Differential TTL, and Switched HV outputs. The module integrates on-board processing, external handshaking, and VXI TTLTRG synchronization for multi-module operation.

Interface Technology IO110VXI — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Interface Technology IO110VXI. 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 Interface Technology IO110VXI 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.
