Control circuit
4.3.5.1 External supply
Using the external supply, the control board, I/Os, fieldbus, sensors (temperatures, humidity,
mounting orientation) and the internal fan remain in operation even if the power unit is discon-
nected.

4.3.5.2 Digital outputs
All outputs are short-circuit proof. They are suitable for inductive loads (without free-wheeling
diode up to 300 mJ max.).
The sum of the load currents at the 24 V outputs of the control card (DO 0...DO 8, X2B.1/3...31
and X3A und X3B) must not exceed 3.4 A.
