The SX400 Series is a dual output timer with two independently programmable, timing interval setpoints. The two outputs can be programmed to operate either simultaneously or in sequence, providing the equivalent operation of two interval timers. The sequential output operation can also be used to provide repeat cycle timer operation. The SX460 has eight programmable time ranges. Time ranges from
99.99 seconds to 999.9 hours are available to allow the use of one unit in many applications. Easy to use minute: second and hour: minute ranges are also available.

The SX400 Series is housed in a standard DIN case (68mm square cutout). The case and front bezel require minimal panel space yet provide easy to use programming keys and an easy to read .36 inch LED display. The four operating modes and the eight time ranges are programmed using rocker switches on the back of the unit. This programming method provides both simplicity and security. The front panel display has a prompted programming routine that shows the user how to program the setpoints

|Output 1 Modes:

||Output 1 is energized at the end of the timing cycle
||Output 1 is energized during the timing cycle
|ONTimed Pulse Output:
||Output 1 is energized for a programmable pulse time up to 99.99 seconds at the end of the timing cycle.
|Timed Pulse and Repeat:
||Output 1 is energized for a programmable pulse time up to 99.99 seconds at the end of the timing cycle with the time cycle automatically repeating.
|Repeat Cycle, ON or OFF Time Cycle First:
||Output 1 is energized and de-energized in repeating operation with either the ON or OFF time period first. The time periods are equal length. Unequal length time intervals can be obtained using the Early Trip prewarn output.
|Output 2 Modes:
||Output 2 can be programmed to operate in parallel with Output 1, providing DPDT relay operation form the two SPDT relays, or it can be programmed as an Early Trip prewarn output that is energized at a predetermined time before the end of the cycle. An example of Early Trip prewarn operation with the ON Delay mode for Output 1 is shown here for reference.
