Digital outputs

The digital outputs control four "high-side" switches. They function like a contact, where one side
is connected to the positive supply of the RTCU unit, and the other is the output. The switches are
protected against short circuit, ESD and electronic kickback from inductive loads such as relays,
etc. The maximum switch-able inductance is 20mH and must not be exceeded.
The digital outputs are supplied through the X1 power connector that also supplies the rest of the
RTCU unit. As this power is also the RTCU NX-200 main power, a power-fail would also affect
the digital outputs.
The RTCU unit offers a very advanced power management that makes it possible to have one or
more outputs enabled while the RTCU is in low power mode. Please consult the RTCU IDE
documentation for additional information.

Please note: Special attention to wiring must be taken; if the total current consumption of the
digital outputs exceeds 1.5A, then PGND must be used as a return path for the output(s).
If the total current consumption of the digital outputs exceeds 5A, the two SUPP pins and PGND
must be used for supply.
