Can a pulse signal drive two display instruments in parallel at the same time?
Thread Content
The flow meter’s pulse signal has only one output; is it possible to connect two meters simultaneously?
Sure! But it depends on your acceptance form; you need to study in detail how to make the wiring!
I would like to send a signal to the digital display on site, and additionally send another signal to the PLC system. Is it possible to generate two separate signals in this simple manner?
Whether it can be simply combined depends on whether the signal source outputs voltage pulses! Some have optocoupler output; in that case, it depends on whether a digital display is used for power supply PLC? External power supply again?
It should be possible. I need someone with experience and knowledge to pass by here and give some advice.
Can they be used in parallel? 1. What is the output load capacity of the pulse signal? Can it drive two devices for signal acquisition? Generally, for pulse signals, the input impedance at the acquisition end is high, so they can be used in parallel. 2. It is necessary to analyze whether connecting the signal grounds of two acquisition devices through pulse signals will affect the normal operation of both devices. If there is no impact, then it can be used; if there is an impact, optocoupler isolation must be added.
Parallel connection is not easy to implement; series connection is simpler. You can add a display instrument and a current transducer to send the signal to the PLC. If a parallel connection is indeed necessary, you can use a module that converts pulses into two currents.
No, let’s add a conversion module
