3.3 Relay Outputs
Figure 11 shows the BL2000 relay contact connections. 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.
Figure 11. BL2000 Relay Output Contact Connections
The relay is driven by PA0, which is the same Rabbit 2000 parallel port that drives OUT0
and LED DS4. OUT0 therefore works in parallel with the relay output.
The relay included on the BL2000 has contacts rated for 1 A @ 30 V DC or 300 mA @
120 V AC. When using the BL2000 in a CE-certified application, the voltages handled by
the relay must not exceed SELV levels (42.4 V AC peak, or 60 V DC).
