Hi all,
I am looking to replace an old set of trip amps that used a complex thermocouple setup that did averaging electrically. I will run back all the 8 thermocouples to the panel and average in the controller so we know the state of each device. Trouble is there is little space and I need a display to replace the old analogue gauge and to show the device faults etc. Is there any controller that can handle TC inputs, three digital outputs and has a rudimentary display to show the 8 temperatures?
I know how I would do it with a basic CompactLogix CPU, 2x IY4, OW4 and a 2711R-T4T but the customer is looking for a dirt cheap solution!
Any thoughts, I only use Rockwell so don't know the market for lower end controllers, haven't even used a MicroLogix yet.
PS. This is in a 1970s relay logic panel.
