2.2.3 Electrical characteristics

2.2.3.1 +24 VDC power supply

Danger!
This device is only permitted to by supplied by a SELV/PELV power supply or with safety extra-low
voltage (SELV) per EN 60950.
The 3-pin male connector required for connecting the power supply is not included in delivery. It can be ordered
from B&R using model number 0TB103.9 (screw clamp terminal block) or 0TB103.91 (cage clamp terminal block).
For the pinout, see the following table. The supply voltage is protected internally by a soldered fuse (10 A, fast-
acting) to prevent damage to the device in the event of 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 destroyed in the event of error.
