2.9.6 +24 VDC supply voltage
The Automation PC 620 has a 24 VDC ATX compatible power supply. Depending on the system
unit, the power supply provides the following maximum performances (in watts).
The 3-pin socket required for the supply voltage connection is not included in delivery. This can
be ordered from B&R using the model number 0TB103.9 (screw clamp) or 0TB103.91 (cage
clamp).
The pin assignments can be found either in the following table or printed on the Automation PC
620 housing. The supply voltage is internally protected (10A, fast-acting), so that the device
cannot be damaged if there is an overload (fuse replacement necessary) or if the voltage supply
is connected incorrectly (reverse polarity protection - fuse replacement not necessary).

Important!
The pin's connection to the functional ground (pin 2, e.g. switching cabinet) should
be as short as possible. We recommend using the largest possible conductor cross
section on the supply plug.
