5.10 S0 output rate
The energy meter is equipped with two pulse outputs (forward and reverse) which are optically isolated from the
inside circuit. It generates pulses in proportion to the measured consumption for purpose of remote reading or accuracy tes-
ting. The pulse output is a polarity dependent, open-collector transistor output requiring an external voltage source for correct
operation. For this external voltage source, the voltage (Ui) should be lower than 27V DC. The maximum switching current
(Imax) is 100mA. To connect the impulse output, connect 5-27V DC to connector 18/20 (collector), and the signal wire (S) to
connector 19/21 (emitter).
