A/D conversion time

500µs × number of selected channels

(If channels use the digital filter(s): 5ms × number of selected

channels)

Insulation

method

The photo-coupler insulates the analog input area from the PLC.

The DC-DC converter insulates the analog input area from the power supply unit.

Channels are not insulated from each other.
