One is a thermostat is a solid state relay used to control the heating pipe, how should the connection
You of course, to die, your solid-state relay signal input point (3,4) to receive AC voltage signal. You are the temperature controller PID output 3, 4 is the DC voltage signal
Temperature control 7,8 then 220V AC work electricity, 1,2 then K type thermocouple, 3,4 for the pulse width output solid state control end, solid output string in the electric heating circuit. The normal is so connected, but you have a selection of this problem, the thermostat pulse width output is 12VDC, your solid state for the 220VAC drive, you can try the next 11,12 string 220VAC connected solid state control, or for solid state it.
Temperature control table 3-4 ends, and solid-state relay corresponding to 3-4 points connected to one end of the heating pipe directly connected with the zero line. The other end of the heat pipe is connected to the solid state relay 1. Solid state relay 2 is connected with FireWire;
Temperature control table solid state is the current industrial automation control common control circuit, is the general circuit engineers must be familiar with;
All manufacturers of temperature control table control solid state relay labeling methods are the same. SSR is the solid state relay control output.
