The BO source power selection jumpers determine whether a BO provides internal power (sourced from the field controller) to the output load (INT position) or requires an external power source (EXT position) for the output load. Figure 1 shows an example of a controller BOs and the associated power selection jumpers to the right of the BOs terminal block.
Important: Do not connect an external power source to a BO when the BO power source jumper is in the internal power (INT) position. Connecting external power to a BO that sources internal power can damage the controller and void any warranties.
