Terminal assignment of the DI 32 x DC 24 V
The figure below shows the assignment of channels to addresses (input byte x up to input byte
x+3).
Redundant use
External diodes must also be wired to the inputs so that, for example, no impermissible states
are detected when one of the two redundant modules is pulled out.
Suitable diodes include diode types from the 1N4003 to 1N4007 series or any other diode with
U_r >=200 V and I_F >= 1 A
