Please, calculate the voltage drop by checking the conductor specifications for characteristic
resistance values. The voltage drop shall not exceed 2 V.
Example:
Length = 100 m/328 ft
U = 12V, I = 1A, maximum U
i.e. RAWG18 (acc. specs) = 6.385

Critical condition! Install the power supply closer to the controller.
Notice!
These specifications apply to power supply, readers, relay outputs, and extension interface.
Regarding inputs, specific voltage-drop values need to be taken into account. Refer to
Connecting Analog Input Devices, page 26.
