INSTRUCTIONS FOR CONNECTING THE IMPULSIVE OUTPUTS OF THE B METERS
The pulse emitter IWM-PL3/PL4 modules with inductive principle provide polarized Open Collector (OC)
NPN type outputs (they do not provide a "clean" contact).
The reference scheme is the following:
The figure shows that the OC1, OC2, OC3 outputs (where we'll connect the impulse emitter, the PLC input
or any device that receives the pulses) are connected to an NPN type transistor (J1, J2, J3 in the figure).
The output operation is as follow:
"When a pulse is generated the output transistor is a switch that closes the contact to ground".
