Description
The model 439 is an all solid state delay-on-make
timing module operating a set of relay contacts as the output. When operating voltage
is applied the timing period begins. At the end of the delay period, provided by an
external resistor. The timer is protected by transient absorption devices that provide for
a highly reliable timing device when used in high electrical transient applications.
