Switch State Sensing
The switch state detection terminals are located in the E module.
Required settings Options/description
Quantity Switch
Funct/Port E: Switch (selected automatically when the
corresponding Quantity setting is activated )
Also check the Sound setting. The option
Change means that MC5P beeps every
time the switch changes its state. When
using options Open or Closed the sound
is continuously on when the switch is
open respectively closed.
The contact should be free of external po-
tential. If this is not possible, use DC volt-
age within the range -10 V to +30 V. MC5P
shows voltages above approx. +1.5 V as
open contact and voltages below approx.
+1.5 V as closed contact.
Hint!
Switch state detection may also be used for binary signal detection.
