So I have been looking over some of P-J's wiring diagrams as I am planning a 50A 2 element 2 pump HERMS setup and I am confused as to why you need to have an SSR switched with a PID then fed to a magnetic contactor. Couldn't you just use a relay output PID fed directly to the contactor and do away with the SSR all together?
I work with this stuff a little as I am in the plastics industry and work around ovens and melt tanks so I understand most of what is necessary but the redundancy seems unnecessary.
Thoughts?
