Coyote (BL2500)
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 poK 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.
