Proline Promag H 200

Load

Ex connection data

Endress+Hauser
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
line resistance must be observed to ensure adequate terminal voltage at the device. In doing so,
observe the minimum terminal voltage
