The EX1200-5001 is a high-density general purpose 2 A 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. Up to 480 SPST relays can be accommodated in a 1U 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.
The EX1200-5001 can be controlled programmatically using IviSwtch-compliant calls. Both path
level programming and individual relay control are available. Refer to the host driver
documentation for additional details.
