A new client asked us to run shielded 18-2 cables from a contact closure on each of the 26 mold machines in a factory. Those cables terminate 250ft into a PLC enclosure with 26 pair contacts.
Which devices would you recommend. Hard wiring is the most time consuming and labor intensive, but the least amount of problems down the road, but expansion becomes a problem.
The contact closure tells the PLC that a part has been completed, so you will be getting 26 monitor events every 30 seconds or so.
The mold machines are typically in a pod configuration, I can probably connect 8 of them to a transmitter.
could I use a 32 unit receiver , then output those to the inputs on the PLC ?
