The high-speed (200 kHz) SBs (SB 1221 and SB 1223) support only sinking inputs. The
standard SB 1223 supports only sourcing inputs.
The high-speed (200 kHz) outputs (SB 1222 and SB 1223) can be either sourcing or sinking.
The high-speed (200 kHz) outputs (SB 1222 and SB 1223) can be either sourcing or sinking.
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.
