Product Discription
Input modules accept contact signals from the field. SDV144 can be made dual-redundant.
These voltages show the case using the field power supply floating. When the field power supply is grounded, the system
(functional) ground is connected to the field ground, which is not isolated. For the higher noise immunity, floating the field
power supply is recommended.
When the withstanding voltage of the field power supply between the secondary side and the ground is lower than the value
shown in the table above, these voltages are adopted as the withstanding voltage of the field power supply
