3.8 Relay Output Circuit (LP3500 only)
A bistable relay is stuffed on LP3500 models only at position K1, and the relay contacts
are accessed via screw-terminal header J8. The relay can switch up to 1 A at 30 V DC.
The relay is set via Parallel Port PG4 on the Rabbit 3000, and is reset via Parallel Port PG5
by a 10 ms pulse. The relay resets when the LP3500 resets, and operates only in the nor-
mal power modes.
NOTE: The relay does not reset automatically when power is removed from the
LP3500.
Figure 18. Relay Output Circuit
NOTE: Switching the relay may consume up to 120 mA during the roughly 10 ms that it
takes for the relay to switch. Make sure that your power supply has sufficient capacity
to handle this surge current to avoid putting the LP3500 into the power-save mode. The
relay does not consume any current while it is in the NO or the NC position and is not
switching.
