Hello everybody,
I work in the field of industrial computing and sensors. However, I am not an automation specialist. My expertise is more on the side of the Industrial Internet of Things.
I often need to connect sensor readers to sensors that are already connected to PLCs. Since these PLCs are used by my customers to control their processes, it is not an option for my sensor readers to cause interference with the signals read by the PLCs.
Could you please give me the rules to respect according to different scenarios (4-20mA, voltage signal, pulse counters, etc.) to be able to install my sensor readers correctly. For example, someone has already told me that there is an impedance issue to be respected.
Thank you in advance
Bert
