The DeltaV system supports the DI, 8-Channel, 24 VDC, Isolated card
and the Series 2 DI, 8-Channel, 24 VDC, Isolated card in Simplex mode.
Installation Notes
The I/O terminal block is
recommended to provide screw terminations for field wiring for the DI,
8-Channel, 24 VDC, Isolated card and the Series 2 DI, 8-Channel, 24 VDC,
Isolated card in Simplex mode. Optional terminal blocks are the fused I/O
terminal block and the 16-pin mass termination block.
If you use a mass
termination block with the DI, 8-Channel, 24 VDC, Isolated card, refer to the
termination block specifications for the input rating for each block. Those
specifications might be more restrictive than the specifications listed in the
following table.
