Wiring a Contactor to On-board Output on the WatchMon supervisor
When connecting to the controlled Outputs (that are using mosfet's) make sure that these loads do not have large inrush currents. Watchmon supervisor and expansion boards outputs are rated to 3A (default), they will fail when the inrush currents exceed their rating (x2 even for micro/milliseconds).
For large (or unknown) loads make sure you use a external relay/SSR (solid state relays) that is appropriate for the rated purpose.

Locating Input & Output Connections on WatchMon4
The inputs and outputs on the WatchMon4 can be configured on the Hardware - Expansion settings as inputs and Outputs A. See the Hardware Configuration - Expansion Settings
The options for what to trigger the contactor as at WatchMon Toolkit software version 2.10 are
