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.
