(1) Maximum power dissipation applies when using 28.8 V DC module supply and maximum power dissipated for all eight outputs in
the ON state.
(2) Input off-to-on filter time is the time from a valid input signal to recognition by the module. Input on-to-off time is the time from a
valid input signal to recognition by the module.
(3) Use this conductor category information for planning conductor routing. Refer to the Industrial Automation Wiring and Grounding
