No. That's a good way to kill your PID. SSRs use low voltage DC on the control side. If your PID has a SSR driver, pin 8 and 9 are low voltage OUTPUTS. An SSR driver is not a relay. You will see on your SSR that one side will say 240V AC and the other side will say something like 3VDC-34VDC. You need to connect those low voltage terminals to pin 8 and 9.
