I would like to ask the experts! It mainly alerts by setting an upper pressure value on the digital display; as for how to establish an interlock reaction with the shut-off valve, what equipment needs to be added? No need for DCS or PLC. Please advise!

A PLC or DCS is required to cut off the feed when the reactor pressure is too high.

Adding an intermediate relay will do; it’s a very simple form of control
