"The digital input module has a width of only 12 mm and has 8 channels in 2-wire connection technologyThe module registers binary control signals from the field range, e.
g.
from sensors, transmitters, switches or proximity switchesThe module is equipped with push-in CAGE-CLAMP® connections, enabling single-stranded conductors to be inserted directlyAn RC filter is connected upstream of each input channel with a time constant of 3.0 ms for suppressing interferenceThe signal state of each channel is indicated by means of a green status LEDField and system levels are galvanically isolated from one anotherTo open the push-in CAGE CLAMP® connections, an actuating tool with a 2.5-mm blade is required (210-719)"
