Date Code 20080918 Instruction Manual SEL-749M Relay
Installation
I/O Configuration
I/O Card (3 DI/4 DO/1 AO). Supported in Slot D, this card has three
digital inputs, four digital outputs, and one analog output. Table 2.6
shows the terminal allocation.
I/O Card ( 8 DI). Supported in Slot C only, this card has eight digital
inputs. Table 2.7 shows the terminal allocation.
Changing cards, or expanding the initial number of cards requires no card
programming; the relay detects the new hardware and updates the software
accordingly (you still have to program the I/O using the SET command).
Following a change in configuration, the relay is always disabled until you
accept the new relay configuration. To change the configuration, perform the
following steps.
