must be connected to the +/- terminals.
With an open relay contact, the current leakage through the contact protection is
0.7 mA
(at 230 V / 50 Hz). This should be taken into account for smaller AC loads.
If this is too high, it is recommended to use a PCD3.A220 module (without contact
protection).
Watchdog: This module can be used on all base addresses;
there is no interaction with the watchdog on the CPUs.
