3.7.1. Binary inputs
MT-021
module is equipped with 4 optoisolated binary inputs marked as I1...I4. They
may work only in positive logic. All binary inputs have same reference - module's
electrical ground - negative pole of the power supply connected to GND pin.
The change of the input signal sets the alarm flag, connected with the corresponding
binary input respectively as Bi 0->1, Bi 1->0 or Bi 0->1|Bi 1->0.
