Redundant Discrete Output 40-Pin Mass Terminal Block specifications

Installation notes

This terminal block is used to terminate wiring for a redundant pair of S-series DO 32-channel 24 VDC high-side Plus cards. Set the terminal block key to B4 before installing the card.
The mass terminal block has two, 20-pin IDC headers that split the 32 channels into two, 16-channel headers. Each of the two-row headers accept a 20-pin 1-for-1 passthrough cable with 2x10 header connectors.
When the redundant DO, 32-Channel, 24 VDC high-Side Plus card is used with the Redundant Discrete Output 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 Output 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.
The return connection is made internally between the mass terminal block and the DO 32-channel 24 VDC high-side Plus card. No external wire is required.

Note

The termination fault detection feature is available only when the redundant DO, 32-Channel, 24 VDC high-Side Plus card is used with the Redundant Discrete Output 40 Pin Mass Termination Block connected to the Pepperl+Fuchs HiD Series Boards when IS barriers are required.
