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 interaction 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.Hardware Manual for the PCD2.M5 Series│Document 26/856; Version EN 09│2012-01-256-31Saia-Burgess Controls Ltd.
