8.2 TR48DIOC
The output specifications of the TR48DIOC differ from those of the SR7000 (i.e.,
source type). The polarity is the same as the output polarity of I/O printed board
X8HI of this controller.
For the input specifications, a bidirectional photocoupler is used in the input circuit,
and it is possible to change over the source type or sink type by the selection of
INCOM*.
