3.3 Schematics for wiring inputs
The 4GT communicator has two input terminals (IN1, IN2) for connecting NO, NC, NO/EOL, NC/EOL,
NO/DEOL, NC/DEOL type circuits. Default input setting – NO. The input type can be changed in the
myMonitoring App.
Connect the input according to the selected input type (NO, NC, NO/EOL, NC/EOL, NO/DEOL,
NC/DEOL), as shown in the wiring diagrams below.
Note:
If more inputs or outputs need to be connected to the communicator, or if you want to
connect a temperature sensor, connect the iO series wired or wireless output expander.
