The SMX-5001 is a high-density general purpose 2A SPST switch module designed for systems where individual relays can be used to route signals to/from the units under test (UUT) or combined externally to form user-defined configurations. These relays are commonly used to create complex signal distribution networks that can be reconfigured through different wiring in test adapters. The modules can also be configured with other SMX series and EX1200 series switch modules as part of a flexible system switch design.
