If you're working on a project that requires switching high-voltage signals in a compact and reliable manner, the M910 series from Keysight Technologies might just be what you need. These multiplexers are designed to handle up to 100VRMS and 1A per channel, making them suitable for applications where you need to switch multiple signals efficiently without worrying too much about power consumption.

The M9101A, M9102A, and M9103A models offer different channel counts and wiring configurations to fit various needs. The M9101A comes with 64 channels and dual-wire capability, ideal for complex test setups where you need to manage a large number of signals simultaneously. The M9102A, with its 128 channels and single-wire configuration, is great for scenarios where you want to maximize channel density while still maintaining reliability. Lastly, the M9103A offers 99 channels with dual-wire capability and uses electrically operated relays instead of tongue-and-groove relays, which can be beneficial for applications requiring faster switching speeds.

One thing worth noting is that these multiplexers use Reed relays, which are known for their long lifespan and low maintenance requirements. This makes them particularly attractive for long-term testing and measurement applications. Engineers tend to reach for this series when they need a robust solution that can handle high-voltage signals in a space-constrained environment, such as in PXI systems or other modular test equipment. The reliability and durability of these components ensure that your setup remains stable even under demanding conditions.
