Digital Outputs

The digital outputs control four "high-side" switches. They function like contacts, where one side is
connected to the positive supply of the RTCU unit, and the other side is to the output. The switches
are protected against short circuits, ESD, and electronic kickback from inductive loads such as a relay.
The maximum switchable 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 the power is also the RTCU LX2 pro main power, a power fail would also affect the
digital outputs.
The RTCU unit offers advanced power management that can enable one or more outputs 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 must be used
for supply.
