SEL-787 Relay Instruction Manual Date Code 20150130
Installation
I/O Configuration
I/O Card (4 DI/3 DO)
Supported in any nonbase unit slot (Slot C through Slot E), this card has four
digital inputs, one Form-B digital output (normally closed contact output) and
two form-C digital output contacts. Table 2.11 shows the terminal allocation.
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-787 offers flexibility in tailoring I/O to your specific application.
The SEL-787 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 cards are available for the SEL-787 in Slots C, D,
and E. Optional communications cards are available only for Slot C, an RTD
card is available only for Slot D, and 1 A/5 A CT combinations for voltage/
current cards are available only on Slots E and Z. Figure 2.2 shows the slot
allocations for the cards. Because installations differ substantially, the
SEL-787 offers a variety of card configurations that provide options for many
diverse applications. Choose the combination of 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 will be lost. For example, if a 4 DI/
4 DO card is installed in Slot 4 (Slot D), the SEL
OGIC settings OUT401–
OUT404 would be available. If OUT401 = IN101 and 51P1T and the card is
moved to a different slot, then the OUT4xx settings will be lost. This is true for
all the digital and analog I/O cards.
