3.4 Power Board
The "C6PWR" Board
This board contains the power supply for the entire camera. It is also responsible for the galvanic
separation of the signals, and tailors the levels of the PLC-signals (4 inputs, 4 outputs).
The camera is supplied with a nominal voltage of 24 V (+/- 20%). An electronic stabilization of the
supply voltage is not necessary. The camera is internally galvanically separated from the supply
voltage by means of a DC/DC converter, to avoid common ground loops and electromagnetic
interference. A reverse-voltage protection diode protects the camera in case the supply voltage poles
are swapped.
An I/O processor performs PLC I/O , and also monitors PLC voltage failures and overcurrent.
