The last two letters of the order number indicate the
rated frequency fn and the auxiliary voltage Uaux of
the relay as follows:
AA equals fn = 50 Hz and Uaux = 80…265 V ac/dc
CA equals fn = 50 Hz and Uaux = 18…80 V dc
DA equals fn = 60 Hz and Uaux = 80…265 V ac/dc
FA equals fn = 60 Hz and Uaux = 18…80 V dc
