I'm using Siemens CPU 1214C, DC/DC/DC. So far I only connected the CPU to power supply.
I had been able to create PTO. When I check the output signal with my oscilloscope at 50Hz, the square pulse is distorted.
But if I put a resistor in between output and ground and I measure it. It give me perfect square wave pulse.
Maybe the CPU is damaged. There had been 4,5 fuse break current overload to the CPU. I had checked input and output, the CPU seems likely works fine.
Can anyone explain me this? Thank you!
