User manual

CyBro-2 series DC transistor outputs contain protective clamping
diodes that are adequate for most applications. In case of large or
frequently switched inductive loads use external suppression
diodes (type 1N4001 or equivalent).
You can also use diode suppression for DC loads relay switching.
For AC loads relay switching use
resistor/capacitor suppressors
across either the load or the AC
outputs.
R > 0.5 x Vrms [Ů]
C=2to4nFforeach 10VA of load
You can also use metal oxide varistor
(MOV) to limit peak voltage.
Working voltage of the MOV should be
at least 20% greater than the nominal
line voltage.
