ALTERNATIVE CONNECTIONS
188
MATRIX 220
Figure 5 - PNP Output Connection
Figure 6 - NPN Output Connection
Figure 7 - Push-Pull Output Connection
CAUTION
For NPN output connections, the external interface voltage (Vext) must
not exceed the Matrix 220 power supply source voltage (Vdc) otherwise
correct output functioning cannot be guaranteed.
CAUTION
For Matrix 220 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 rec-
ommend connecting them through the CBX, which must be powered sep-
arately.
