B.4.3 CMOS Digital Outputs
If the stepper-motor option is not used, eight CMOS-level digital outputs are available at
J10, and can each handle up to 25 mA.
B.4.4 Sinking Digital Outputs
Four sinking digital outputs shared with LEDs DS3–DS6 are available at J12, and can each
handle up to 500 mA. Figure B-6 shows a wiring diagram for a typical sinking output.
B.4.5 Relay Outputs
Figure B-7 shows the contact connections for the relay on the Prototyping Board. A diode
across the coil provides a return path for inductive spikes, and snubbers across the relay
contacts protect the relay contacts from inductive spikes.
The relay is driven by pin PA4 of the RCM3900 module via U8, and is controlled by PE7
and PG5 as shown in the sample applications.
