INSTALLATION INSTRUCTIONS TIME DELAY RELAY - DODO DELAY ON DROP-0UT Model 091-103-012 The Model 091-103-012 Time Delay Relay operates in a +12 volt electrical system. The relay contacts transfer immediately upon the application of an input signal and remain closed after the signal is removed for the length of the specified time interval. The range of output times as well as the factory setting is shown in the table. The output relay contacts are capable of switching 30 amperes. An adjustment is provided to vary this time at installation. See figure 1. An LED indicator adjacent to the terminal strip is lit whenever the relay is energized. Figure 2 illustrates the Time Delay Relay applied to a typical lighting circuit. Time Delay Adjust NOTE: The run/calibrate switch speeds up the time delay interval by a factor of 128.
