SDV144-S13 YOKOGAWA Analog Digital I/O Module Outputs 4 To 20 mA Signals To The Field Dual Redundant
 
 
Description:
 
This GS provides the hardware specifications of the digital I/O modules that can be installed in the Safety Node Unit and Safety Control Units.

• 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.
• Number of input channels which a user can use and external power supply are restricted in case of SDV144-S£C. Refer to “ProSafe-RS Outline of I/O Modules (for FIO)” (GS 32P06K60-01EN).
• The contact rating and the external power supply of SDV144 style code S1, S2 and S3 are 24 V DC ± 5 %.
• : When connecting SDV144 and SED4D terminal board using the dedicated signal cable, the withstand voltage is 500 V AC (between input signal lines and system). If MIL connector cables are used, the withstand voltage depends on their cable’s electrical specifications.

 
Additional Information:
 
Input modules accept contact signals from the field. SDV144 can be made dual-redundant.
