The Astronics / EADS / Racal 1260-30D is a C-size VXIbus multiplexer module engineered for signal routing and switching in automated test systems. This single-slot module configures as eight independent 1×5 two-wire multiplexer networks, enabling flexible connection of multiple input signals to a common output or vice versa. The 10 MHz bandwidth supports switching up to 250V at 2A, making it suitable for DMM scanning, continuity testing, and general UUT point verification.
