3.3.2 Digital Outputs
The Coyote has eight digital outputs, OUT0–OUT7, each of which can sink up to 200 mA.
Figure 12 shows a wiring diagram for using the digital outputs in a sinking configuration.
Figure 12. Coyote Digital Outputs
+K is an externally supplied voltage of 3.3–40 V DC, and should be capable of delivering
all the load currents. Although a connection to a +K supply is not absolutely required with
sinking outputs, it is highly recommended to protect against current spikes when driving
inductive loads such as relays and solenoids.
Connect the positive +K supply to pin 1 of friction-lock connector terminal J10 and the
negative side of the supply to pin 2 of friction-lock connector terminal J10. A friction-lock
connector is recommended to connect this supply because the +K inputs are not protected
against reverse polarity, and serious damage to the Coyote may result if you connect this
supply backwards.
