Note
The high-speed (200 kHz) SBs utilize "sourcing" inputs. The standard SB (20 kHz) utilizes
"sinking" inputs. Refer to the specifications for the digital inputs and outputs (Page 249).
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 0V, which means
that a sinking load will be turned ON.
