All parameters are specified at 24Vdc input voltage, 8x5A output currents, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
19. Safety Features And Protection Features
Isolation resistance >10MOhm At delivered condition between power port and
signals, measured with 500Vdc
>10MOhm At delivered condition between power port and
housing, measured with 500Vdc
>10MOhm At delivered condition between signals and housing,
measured with 500Vdc
Output over-voltage protection max. 500Vac Power port to signal port
max. 500Vac Power port / signal port to housing
Class of protection III A PE (Protective Earth) connection is not required
Degree of protection IP20 According to EN/IEC 60529
Over-temperature protection Not included
Internal input fuse Not included
Internal output fuses Not included
Input over-voltage protection max. 31.4Vdc No harm or defect of the unit
Reverse input polarity protection Not included Make sure that the input voltage polarity is correct
before applying the input voltage.
Touch current (leakage current) The leakage current which is produced by the module itself depends on the
input voltage ripple and need to be investigated in the final application.
For a smooth DC input voltage, the produced leakage current is less than
100μA.
