LED
display DATA 0 - 7 Input status display for all points,
lit at ON, internal logic side
STATUS 0 - 7 Interrupt point display, returned to OFF
by resetting the interrupt flag
Interrupt function Generates interrupt signal for T3 when
input status of each point is changed.
Interrupt timing can be selected for each
point either rising, falling or both edges. Note (2)
Number of modules on T3 Max. 8 modules
Note (1) The normal or high speed mode can be selected by internal jumper plug
settings. Refer to section 3.1.
The delay time includes the input filter and internal sampling.
Note (2) The interrupt timing is selected by DIP switches. Refer to section 3.2.
