Description
The model 4383 is an interval
timing device that is has three sets of relay output
contacts. Two sets are normally open and one set is normally closed. When operating
voltage is applied, the output contacts transfer for the full duration of the preset
timing period, or until the operating voltage is removed. The model 4383 is protected
against high electrical noise as is found in electric transit cars and locomotive type
applications. Both fixed timing and remotely adjustable timing models are available. The
polarity of operating voltage does not have to be observed.
