Belt Conveyor Zero Speed Switch

Please specify pulse sensor type, PLC type, and available I/O. Does this conveyor use drives for it's motors? What kind? How many? Is the conveyor speed PLC controlled? Explain "moniter". Standing by.

Using kanna electronis type sensors and relay unint. those conveyors are working in with out drives.

Moniter will sense the plus frm sensor in the moniter one continious plus generate and same will go to PLC. In PLC logic is made when plus came low it will trip the conveyor.

Not knowing all of the parameters and requirements makes all solutions hard:

But given that you have conveyors, that most likley have chain drives, they will have sprockets that drive the chain.

"Old School" the easiest method is to use a sensor on the teeth of the sprocket, in logic you can see the pulse when the teeth are moving, and when they are not.

This has been used for many years and is very dependable.

"If this fits use it, if it does not, member it, some times the simple things work, some times they don't"

I used to design belt conveyors, and zero speed sensors on the tail pulley shaft were the common method used for verifying proper operation.

Can i get the diagram of your systems, which i can also implement in my ares.
