Installation
I/O Configuration
I/O Card (14 DI)
Supported in any nonbase unit slot (Slot C through Slot E), this card has four-
teen digital inputs. Table 2.16 shows the terminal designations.
Card Configuration
Procedure
Changing card positions or expanding on the initial number of cards requires
no card programming; the relay detects the new hardware and updates the
software accordingly (you still have to use the SET command to program the
I/O settings).
The SEL-751 offers flexibility in tailoring I/O to your specific application.
The SEL-751 has six rear-panel slots, labeled as Slots A, B, C, D, E, and Z. Slots
A, B, and Z are base unit slots, each associated with a specific function.
Optional digital/analog I/O, communication, RTD, arc-flash detectors, and
voltage/current cards are available for the SEL-751 in Slots C, D, and E.
Figure 2.2 shows the slot allocations for the cards. Because installations differ
substantially, the SEL-751 offers a variety of card configurations that provide
options for the many diverse applications. Choose the combination of option
cards most suited for your application.
Swapping Optional I/O Boards
When an I/O board is moved from one slot to a different slot, the associated
settings for the slot the card is moved from are lost. For example, if a
4 DI/4 DO card is installed in Slot 4 (Slot D), the SEL
OGIC control equation
settings OUT401–404 would be available. If OUT401 = IN101 AND 51P1T,
and the card is moved to a different slot, then the OUT4xx settings are lost.
This is true for all the digital and analog I/O cards.
