2.3 Electrical characteristics
2.3.1 +24 VDC power supply
The 3-pin male connector required for the supply voltage connection is not included in delivery. It can be ordered
from B&R using model number 0TB103.9 (screw clamp) or 0TB103.91 (cage clamp).
The pinout is listed in the following table. The supply voltage is protected internally by a soldered fuse (15 A, fast-
acting) to prevent damage to the device in the event of an overload (fuse replacement necessary) or if the voltage
supply is connected incorrectly (reverse polarity protection - fuse replacement not necessary). The device must be
returned to B&R for repairs if the fuse is blown in the event of an error.

2.3.2 Optional Supply voltage VAC
In order to operate the Panel PC with AC power, the optional 5AC902.PS00-00 power supply must be installed
on the Panel PC.
The 3-pin male connector required for the supply voltage connection is not included in delivery. This can be ordered
from B&R using model number 0TB3103.8000.
The pinout is listed in the following table and printed on the housing. The supply voltage is protected internally by
a soldered fuse to prevent damage to the device in the event of an overload (fuse replacement necessary) or if the
voltage supply is connected incorrectly (reverse polarity protection - fuse replacement not necessary). The device
must be returned to B&R for repairs if the fuse is blown in the event of an error.
