2.3 Electrical characteristics
2.3.1 +24 VDC voltage supply
The 3-pin male connector required for the power supply interface is not included in delivery. It can be ordered from
B&R using model number 0TB103.9 (screw clamps) or 0TB103.91 (cage clamps).
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.
