This unit
The Astronics / EADS / Racal 1260-35A is a high-density multiplexer module designed for VXI platforms in aerospace and defense test applications. This single-slot, C-size module delivers flexible signal routing through user-configurable two-wire, four-wire, and one-wire scanner topologies, supporting up to 250 VDC or VAC rms per channel at 1 A maximum with 30 W DC or 62.5 VAC per-channel switchable power. The module operates at 50 MHz bandwidth with low thermal offset, making it suitable for continuity testing, audio switching, and telephone line applications requiring high channel density in minimal physical space.
