Redundant Discrete Input 40-Pin Mass Termination Block

Installation notes

• The Redundant Discrete Input 40 Pin Mass Termination Block provides wiring terminations for a redundant pair of DI, 32-Channel, 24 VDC, Dry Contact, Series 2 Plus cards.
• Set the keys on the terminal block to E3 to match the DI, 32-Channel, 24 VDC, Dry Contact, Series 2 Plus card.
• The mass termination 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 DI, 32-Channel, 24 VDC, Dry Contact, Series 2 Plus card is used with the Redundant Discrete Input 40-Pin Mass Termination Block and the DI Mass Connection Solution, 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 DI Mass Connection Board is enabled and the system detects faults such as a missing cable or missing Mass Connection Board.
• The return connection is made internally between the mass termination block and the DI, 32-Channel, 24 VDC, Dry Contact, Series 2 Plus card. No external wire is required.
