The 8-channel terminal
block is recommended to provide terminations for field wiring for the DI
8-channel 24 VDC isolated card. Optional terminal blocks are the Fused
8-channel terminal block and the 16-pin mass terminal block.
If you use a mass
terminal block with the DI 8-channel 24 VDC isolated card, refer to the
terminal block specifications for the input rating for each block. Those
specifications might be more restrictive than the specifications listed in the
following table.
This card requires an
S-series controller.
