The EX1200-5006 (40 channels) is a general purpose 2 A SPST switch modules designed or 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. Up to 240 SPST relays can be accommodated in a 1U full-rack mainframe.
