Installation Notes
- The Redundant Discrete Input 40-Pin Mass Terminal Block is recommended to provide terminations for a redundant pair of DI 32-Channel 24 VDC Dry Contact Plus cards.
- The common connection for all 32 channels on the DI 32-Channel 24 VDC Dry Contact Plus card is the 24 VDC field power. You must supply an external wire to make this connection.
- When the redundant DI, 32-Channel, 24 VDC, Dry Contact Plus card is used with the Redundant Discrete Input 40 Pin Mass Termination Block and the Pepperl+Fuchs HiD Series Boards, the card can be configured to detect faults in the termination. Two parameters, T1_FAULT_DETECT (for the ribbon cable connection for channels 1-16), and T2_FAULT_DETECT (for the ribbon cable connection for channels 17-32), can be enabled in DeltaV Explorer for the card. When these parameters are set to True, detection of the ribbon cable connection between the Redundant Discrete Input 40 Pin Mass Termination Block and the Pepperl +Fuchs HiD Series Board is enabled and the system detects faults such as a missing cable, missing Pepperl+Fuchs HiD Series Board or a fault condition on an IS barrier on the Pepperl+Fuchs HiD Series Boards. The Pepperl+Fuchs HiD Series Boards are Emerson Alliance Program products.
- This card requires an S-series controller.
Note
The termination fault detection feature is available only when the redundant DI, 32-Channel, 24 VDC, Dry Contact Plus card is used with the Redundant Discrete Input 40 Pin Mass Termination Block connected to the Pepperl+Fuchs HiD Series Boards when IS barriers are required.
