Rockwell Automation 1503 IntelliVAC Contactor Control Module - Series C and later - Manual (Page 29)

3-16 Installation and Wiring
1503-UM052D-EN-P – June 2013
IntelliVAC control may be used for mechanical latch contactors.
A momentary control signal is needed to close the contactor, and a second
momentary control signal is needed to open the contactor. The
momentary open/close commands must be at least 50 milliseconds in
duration.
Refer to Figure 3.10 for a typical mechanical latch control scheme.
Note:
1. A mechanical latch contactor may already be closed when power is
applied to the IntelliVAC control module.
2. It is permissible to apply an open command to the IntelliVAC
module as power is re-applied.
