Dual Supply Interval Timing Module

Model No. 4382 Description:
The model 4382 is an all solid state timer that offers interval timing operation. Intended for service in locomotive and transit car applications, the model 4382 offers excellent transient protection and provides for reliable timing control. The model 4382 is capable of controlling DC loads to 1 ampere at voltages up to 100V DC. Application of the operating voltage supply ‘B’ turns on the remote load circuit connected in supply ‘A’ and starts the timing period. At the end of the preset timing period, the remote load circuit turns off. Should the supply ‘B’ voltage be removed for 100 milliseconds, or longer, during the timing period, the timing period will reset to zero and start again when supply ‘B’ voltage is applied.
