This should be taken into account for smaller AC loads. If this is too high, it is recommended to use a PCD2.A220 Module (without contact protection).Watchdog: This module can be used on all base addresses; there is no interac- tion with the watchdog on the CPUs. For details, please refer to the “Watchdog” section, which describes the correct use of the watchdog in conjunction with PCD2 components.5-35PCD2.A2105.5.2PCD2.A210, 4 relays with break contacts, with contact protectionApplication
