438UP - 

All models are available in voltage ranges from 24 to 240 Volts. They differ only in timing ranges and how the times are set. There is no need to observe polarity with any of this series. Ten volt maximum drop across. 438USAI and 438USAI-2. The timing period is set by connecting a resistor across the center two terminals. A jumper across the timing terminal produces a one second delay, add 10K per second to increase time. 438USA, 438USAI, 438USA-INT, 438USA-PIN, 438USAF. All timing is set by the binary coded DIP switch, which has ten programmable switches enabling the time to be easily set over the entire timing range. 438UP. Timing is controlled by a sealed potentiometer.
