Requirements for the supply unit
Supply voltage
Transmitter
An external power supply is required for each output.
The following supply voltage values apply for the outputs available:
Load
Load for current output: 0 to 500 Ω, depending on the external supply voltage of the power
supply unit
Calculation of the maximum load
Depending on the supply voltage of the power supply unit (U
S
), the maximum load (R
B
)
including line resistance must be observed to ensure adequate terminal voltage at the
device. In doing so, observe the minimum terminal voltage
