The Keysight M9132A is a PXIe modular switching module designed for high-density general-purpose signal routing and control applications. This single-slot PXIe instrument provides 50 independent SPST (Form A) channels using high-speed reed relays, capable of switching signals up to 100 Vrms at 1 A with 25 W maximum power handling. Ideal for powering devices under test on/off, actuating external relays, solenoids, and precision signal switching in automated test systems.
