7.2 Flow meter with active 24 V pulse output  MULTICAL 801 can be direct connected to ”industrial” flow sensors with 24 V active pulse output on terminals 10B and 11B for V1 and terminals 69B and 79B for V2. If the only output of the flow meter used is a passive one, MULTICAL 801’s internal auxiliary supply on terminals 97A and 98A is used.Technical data for the optoisolated pulse inputsPulse input voltage12…32 VPulse currentMax. 12 mA at 24 VPulse frequencyMax. 128 HzPulse duration:Min. 3 msCable length V1 and V2Max. 100 m(drawn with min. 25 cm distance to other cables)Galvanic isolationInputs V1 (10B and 11B) and V2 (69B and 79B) are both individually isololated and isolated from MULTICALInsulation voltage2 kVKamstrup A/S · Technical Description · 5512-571_R1_GB _11.201667MULTICAL® 8017.2.1 Connection examplesFigure 4
