SM7100 Introduction 

A delay can be programmed between relay closures to allow for settling times of other system 
resources. When used with triggers, a controlled synchronous switching system can easily be 
configured. 
 
Safety Interrupt 

This is a programmable fail-safe feature that allows all relays to open based upon the occurrence 
of a selected TTL backplane trigger. This allows signals to be removed from the unit under test if 
a system fail-safe occurs, such as inadvertent removal of a test adapter.
