7.1.2.2 Voltage drop
The max. cable length depends on the voltage drop in the supply voltage cables. The level
of voltage drop is determined by the:
} Cable resistance on the supply voltage cables
} Operating current of the modules
} Load on the modules
To increase the max. cable length, the input voltage can be permanently increased by the
voltage tolerance (see Technical Details).
Calculation example:
} The 0.25mm² sensor cable is used.
Voltage drop per 10m and per 100mA: 0.15 V
