Description
The mode 4387 is a Delay
On Make timing device that incorporates a true delay-on-break timing feature. The
feature that makes the delay-on-break a ‘true’ delay-on-break, is that the
delay-on-break is initiate by the removal of the operating voltage alone, and does not
require any standby voltage during the delay-on-break timing period. The output is a SPST
normally open set of relay contacts that is sustained in the closed state during the
delay-on-break timing without the aid of any standby voltage.
