Example:
Let’s say we have:
• Proxinet 36
• PXKWD (max consumption 60 mA)
• PX8IR (max consumption 40 mA)
• Sensors connected to the remote input expansion (total consumption 150 mA)
• Connection distance 200 m.
With max consumption of 250 mA in this case we either use a 1.5 mm2 section cable, or a 0.5 mm2 cable plus an auxiliary power
source at the end of the line as shown below:
CABLE RS-485
Screened 2x1,5mm² + 2x0,22mm² twisted
CABLE RS-485
Screened 2x0,5mm² + 2x0,22mm² twisted

Control unit Device on bus
Maximum communication performance is guaranteed by using the specified cable (PXC75). Maximum communication
speed between peripherals is 115,200 baud. If not using the cable specified or if there are problems at installation, the
control unit transfer speed can be decreased (38,400, 9,600, 4,800 and 2,400 baud). The speed of the peripherals will
automatically set.
