I was wondering if anyone else has experienced problems with their universal PLC modules by Spectrum? I've had situations where when I connect a thermocouple signal to the module, the signal fluctuates excessively on the HMI, but when connected to a watlow panel meter, it reads rock steady and accurate.
I've had the same problems with 0-10vDC feedback signals and 4-20mA signals. Sometimes changing out the universal module will fix it and sometimes it does not. Sometimes when changing the module out does not fix it, I wonder if i just have another bad module?
These Spectrum universal modules always seem to be the weak link in the PLC racks. What am I doing wrong? Is it really just noise issues?
I'm a technician with limited programming experience, FYI.
