DESCRIPTION Of THE TERMINALS
6.3.1.1 External supply of the control board
Using the external supply, the control board, I/Os, fieldbus, sensors (temperatures, hu-
midity, mounting orientation) and the interior fan (of 18/19P6) remain in operation even
if the power unit is disconnected.

6.3.1.2 Digital outputs
All outputs are short-circuit proof. They are suitable for inductive loads (without free-wheel-
ing 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.
