Example:
Let’s say we have:
• PROXINET8
• PXIT0 (max consumption 100 mA)
• PX8IR (max consumption 40 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 + twisted 2x0,22mm²

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.
