The Class 388 Adjustable True Off Delay
Relay
combines a Solid State Timing circuit
with a state of the art Magnetic Latching
relay. This combination allows the relay
to Pull-in when power is applied to the input.
Timing starts when power is removed from
the input and at the end of the preset timing
period the relay will dropout.
