BULK WATER METER | HYDRANT TESTER PULSE OUTPUTS The outputs are open-collector circuits. The collector branch contains only 0 O resistance, i.e. there is no internal current limiting. If required, this must be provided externally by a collector resistance of 1 k£2 (at 30 V). The pulse outputs must be operated in floating mode if the M-Bus is connected. Output - type Max. voltage drop at active Max. current through inactive Max. reverse voltage without destroying outputs Pulse duration Open collector (high current sink) Display indication - counter Display range - counter module * Display range...
