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*.

To connect the extension input signal cable, use the connector attached to the
TR48DIOC module [XM2A–3701 (plug type connector), XM2S–3711 (connector
cover)]. Connect the inputs of the TR48DIOC (DI_101 ~ 128 (station 0) and
DI_133 ~ 160 (station 1) to connector INPUT provided on the module surface.
