Overview
The EX1200-5002 is high-density general purpose Form C switch modules 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 these cards can be configured as an SP4T tree, and seven relays can be configured as an SP8T tree.
Since these modules may be used to switch power to the UUT or interface, the digital input lines on the EX1200 series mainframes support the ability to automatically force all relays to their open state if a fault condition occurs. This approach instantly removes all power to the UUT or interface. These modules can be automatically configured in the setup phase at the beginning of each scan step to facilitate test sequencing and control.
