The DeltaV system supports the DI, 32-Channel, 24 VDC, Dry Contact card and the Series 2 DI, 32-Channel, 24 VDC, Dry Contact card in simplex mode and the DI, 32-Channel, 24 VDC, Dry Contact Series 2 Plus card in redundant mode.
Installation Notes
- The 32-Channel terminal block can provide screw terminations for field wiring for the simplex DI, 32-channel, 24 VDC, Dry Contact and Series 2 DI, 32-channel, 24 VDC, Dry Contact cards in simplex mode.
- The 40-pin mass termination block can provide terminations for field wiring for the simplex DI, 32-channel, 24 VDC, Dry Contact and Series 2 DI, 32-channel, 24 VDC, Dry Contact cards.
- The DI Mass Connection Board (single) or the DI Mass Connection Solution (two) can be used to provide an interface to the Series 2 DI, 32-Channel, 24 VDC, Dry Contact card used with the 40-pin mass termination block in simplex mode.
- The Redundant 32-Channel Discrete Input Terminal Block is recommended to provide screw terminations for field wiring for the redundant DI, 32-Channel, 24 VDC, Dry Contact Series 2 Plus card.
- The Redundant Discrete Input 40-Pin Mass Termination Block can be used to provide terminations for a redundant pair of DI, 32-Channel, 24 VDC, Dry Contact Series 2 Plus cards
- The Series 2 Plus DI Mass Connection Board (single) or the Series 2 Plus DI Mass Connection Solution (two) can be used to provide an interface to the DI, 32-Channel, 24 VDC Dry Contact Series 2 Plus card used with the Redundant Discrete Input 40-Pin Mass Termination Block.
- For the Series 2 DI, 32-Channel, 24 VDC, Dry Contact card, the return connection for all 32 channels is the 24 VDC field power ground. You must supply an external wire to make this connection. However the connection is internally made if the 40-pin mass termination block is used and no external wire is required.
- For the DI, 32-Channel, 24 VDC, Dry Contact Series 2 Plus card, the common connection for all 32 channels is the 24 VDC field power. You must supply an external wire to make this connection. However the connection is internally made if the 40-pin mass termination block is used and no external wire is required.
- 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.
Note
The termination fault detection feature is available only 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 connected to the DI Mass Connection Solution.
