Electrical specifications Camera Power Supply Camera
The power supply of the VC Base Family range differs form the VC Professional and VC Optimum
Smart Camera ranges. With the Professional and Optimum cameras it is possible to supply the PLC
outputs with a voltage different from the camera power supply via pin 1 and 9. For instance with the
VC4038 to VC4472 camera models it is possible to supply the PLC outputs with 12V via Pin 1 and Pin
9, if that is the required output voltage for OUT0 to OUT3.
With the
VC4018 and VC4016 and VC4002L
cameras these PLC supply contacts are
internally connected with the camera power supply pin 2. In this case pin 1 and 9 require the
same voltage level as the camera power supply pin 2. Refer to section 6.3.4 for details on the
different PLC interface features.
