Hi, I have been given a couple of Cuttler Hammer logic systems to repair. I don't think you could class them as a PLC as they don't have a processor just discrete Input / Output modules a memory card and another they call a controller.
It seems that the controller scans the inputs and based on what it finds turns on Discrete outputs based on how the PROM has been burned. There is limited timing on another dedicated board.
The cards I have are D120PM10 and D120PM20.
I would love to lay my hands on a manual for this system but I don't even know what it's called.
Looking at the rack it seems that to work at all it must have a full complement of cards as the power supply goes from one card to the next in daisy chain fashion.
Anyone familiar with this old relic?
Thanks
Roy
