The EX1200-5002 is a high-density general purpose 2 A 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. For example, three relays on an EX1200-5002 module can be configured as a SP4T tree and seven relays can be configured as a SP8T tree. Up to 192 individual SPDT or 480 SPST relays can be accommodated in a full rack mainframe.
