Overview
The EX1200-5001 and EX1200-5002 are high-density general purpose 2 amp switch modules designed for systems where individual relays can be used to route signals to/from the 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 a -5002 module can be configured as an SP4T tree and seven relays can be configured as an SP8T tree. Up to 180 individual SPDT or 480 SPST relays can be accommodated in a full rack mainframe for maximum density. The modules can also be configured with other EX1200 series switch modules as part of a flexible system switch design.
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 force all relays automatically to their normally 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.
