(6ES7 222-1BD30-0XB0)

For sourcing outputs, connect "Load" to "-" (shown). For sinking outputs, connect "Load" to "+". Because both sinking

and sourcing configurations are supported by the same circuitry, the active state of a sourcing load is opposite that of a

sinking load. A source output exhibits positive logic (Q bit and LED are ON when the load has current flow), while a sink

output exhibits negative logic (Q bit and LED are OFF when the load has current flow). If the module is plugged in with

no user program, the default for this module is 0 V, which means that a sinking load will be turned ON.
