10 SM7100 Introduction
Programmable Timing Delays
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.
