The Model 091-100-012 Time Delay Relay operates in a +12 volt electrical system. The relay
contacts transfer at some time after the application of an input signal to terminal 3. The input
signal may be 12 volts or a ground as selected by the slide switch adjacent to the
terminal strip. An output relay has contacts capable of switching 30 amperes. A +12 volt
power and ground line are required to operate the time delay circuits. In operation the signal
input to the time delay relay is applied when the first load is energized. At the delay interval
later, the relay closes to operate the second load. The time delay is factory set for either 5 or
60 seconds depending on the model. An adjustment is provided to reduce this or increase it
to the values shown in the table. See figure 1 for time adjustment. Figure 2 illustrates the
Time Delay Relay applied to a High Idle/Hydraulic pump control.
