Information on connecting digital output modules via diodes
● Suitable diodes are diodes with U
_r
>=200 V and I_
F
>= 1 A (e.g., types from the series
1N4003 ... 1N4007).
● It is advisable to separate the ground of the module and the ground of the load. There
must be equipotential bonding between both.
