REAL LIFE PLANT STORIES – “No sign of life”!
That was the “heart stopping” problem description that came along with this OMRON I/O 3G2C7-MC228 unit for repair. There was no input or output! Not really heart stopping exactly, but certainly production stopping! And headache causing for our customer!
What Damaged this I/O Unit?
When our tech team opened up the case of this I/O we found significant damage. The damage was caused by both corrosion and glue. The glue may have come from some previous repair, or even a spill. Corrosion of course comes from either water damage or too much humidity in the work environment.
