Electrical specifications Camera Power Supply Camera
It is possible to supply the PLC outputs with a voltage different from the camera power supply via pin 1
and 9. For instance 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.

PLC output power supply
separated from camera supply
PLC outputs supplied separately via Pin 1 and Pin 9,
common GND of power supply and PLC outputs
In general the camera power supply is regulated in the camera, so an unregulated power source is
sufficient. However the absolute voltage levels specified above - depending on the camera range -
should never be exceeded.
In case of unstable power supply (voltage spikes or power interruptions) it is recommended to backup
the power supply by a capacitor or a battery large enough to prevent power interruptions.
It is recommended to switch on the low voltage supply (12 to 24V) when booting the camera. Some
110/ 220V power supplies increase the output voltage too slow or drop the voltage under load at start
– up which might cause the camera not to boot properly!

The PLC output voltage equals the power supply voltage.
