Hi everyone, I have to load a program in a SLC503 PLC on a old piece of equipment that we purchased. I have no experience with Allen Bradley equipment, and google searches have not yielded any results. The PLC was cycling on and off and during a check of the input power I found it to be 28-29 Volts. I installed a DC-DC power conditioner and now have to much current draw >2amps. Any idea what would cause this? I assume the 24VDC supplied to the CPU is only for the power of the processor and back plane operations. Could something be wrong with one of these?
