CAUTION
For NPN output connections, the external interface voltage (Vext) must not exceed the
Matrix 300N power supply source voltage (Vdc) otherwise correct output functioning
cannot be guaranteed.
For Matrix 300N PoE models, the internal Digital Output circuitry is not powered and
supply power
is not available to any Input/Output devices (Vdc=0). Only input device
signals can be accepted directly on the M12 17-pin connector without power.
For these models, if it is necessary to use Input/Output devices, we recommend con-
necting them through the CBX, which must be powered separately.
