This unit
The Astronics/EADS/Racal 1260-30B is a C-size VXIbus multiplexer module that provides dual 1×20 two-wire switching for signal routing in automated test and data acquisition systems. This electromechanical relay-based module handles switching up to 250 VDC or 250 VAC rms at currents to 2 A, with bandwidth to 10 MHz. It integrates into standard VXIbus chassis and operates under message-based or register-based control via an Option 01 Smart Card, making it suitable for multi-point scanning, continuity testing, and confidence checking via relay coil current monitoring.
