What plc system is this http://cgi.ebay.com/ALLEN-BRADLEY-M...t=BI_Control_Systems_PLCs&hash=item4cf198034d

AB PLC 1 maybe?

I have worked with a plc 2 as we have several of them still running but i have never seen this thing before today.

Any ideas? Not much info about it on google only repair parts.

If you see one of these beasts running...leave the building as fast as you can. To say these things are temperamental is an understatement. I got to play with a few of these in the early 90's. We replaced them with SLC 100's as fast as we could. They always reminded me of a TI5 knockoff.

@ my previous job we had some 4TI sequencers with the hand held programmers and tape loaders.

Doing program changes in these things really sucked.

I have worked with those. Didn't have the programmer just the hand held monitor. On some power surges all outputs would sometimes turn on. Very,very scary. But they were still working after 18 years of service before we replaced them.

Ah yes, the 5TI. It's great fun loading a program away from the shop without the tape loader. I had a co-worker (don't say this can't happen, it did) got frustrated with changing timers on a TCAM, stated pushing buttons randomly and somehow dumped the program! This was 30 minutes before the customer was expecting to see a running machine! I had to hand type in the program using the hand held programmer (the 'calculator-looking' item). A few hundred instructions later we flipped the machine on, made one correction and had a working machine with all of two or three minutes to spare.
