PCD1: 100 mA

PCD2: 200 mA

Short voltage interruptions

(according EN / IEC 61 131-2))

≤ 10 ms with interval ≥ 1 s

1) The loads on the outputs are generally more significant for sizing the supply than the internal power leakage

within the controller

2) When planning PCD2 systems, it is essential to check that the two internal supplies are not overloaded. This

check is especially important where analogue, counter and motion control modules are used, as these may con-

sume a lot of power.
