Maximum resistance for analog loop
Maximum resistance: 0 … 500 Ω (depending on power supply voltage)
In order to ensure sufficient voltage at FLOWSIC30, the maximum loop resistance [Rb] in
relation to the power supply voltage [US] must be considered. The operating range of the
FLOWSIC30 is given in
Maximum resistance can be calculated: Rb ≤ (US – 18 V) / 0.022 A; max. 500 Ω
