Figure 3.43 DS2110 Generic Digital Inputs
Note that:-
Input Impedance
> 5k ohm
.
Voltage Range is
12V to 32V
from Digital-Input to the I_COMMON line. Inputs are protected for input voltages
from –40V to +40V
Input voltages whose magnitude is less than 12V with respect to the I_COMMON line will not be
guaranteed to be recognised as an
active
signal input.
Input voltages whose magnitude is more than 5V with respect to the I_COMMON line will not be
guaranteed to be recognised as an
inactive
signal input
All digital inputs are optically isolated
for noise immunity purposes. All DS2110 digital inputs are isolated
from high voltage circuitry internally
Current flowing
in the digital input implies the
'safer'
of the corresponding active/inactive functions. For
example, when current flows in the clockwise limit switch input, then the limit is NOT active.
