Default setting
NO (Normally Open) for all channels
NO (Normally Open)
A non-damped sensor has an open switching output
(low signal) in this case. The device input detects a low
signal and returns a 0 to the control unit.
NC (Normally Closed)
A non-damped sensor has an closed switching output
(high signal) in this case. The device input detects a
high signal, inverts the signal, and returns a 0 to the
control unit.
