Re: PID temperature controller?
I think there's a misunderstanding of terms. When one compares Contactors to SSRs, the SSR stands for Solid State Relay. I've never heard of someone comparing an SSR to a PID Controller. The two have nothing to compare. The PID controls when the internal relays or SSRs are under power using the parameters stored. The SSR is simply an electronic relay to turn the heating elements on. It replaces a contactor/relay. Both need power to switch.
To eliminate any confusion on this board, I suggest we maintain that SSR stands for Solid State Relay as most are accustomed.
