HART load
• Min. 250 Ω
• Max. 500 Ω
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

侑 (19 V - 13 V): 0.022 A = 273 Ω
Low flow cut off
The switch points for low flow cut off are preset and can be configured.
Galvanic isolation
All inputs and outputs are galvanically isolated from one another.
