Interposing Relay Panel Question
Been looking at some drawings of existing platform and I saw a drawing about Interposing Relay Panels. Went and searched some info but not much. Explanation was it's used to amp the signal from DCS/PLC and send them to the control elements like control/shutdown valves, trips & stuff.
Would like to know the true reason for an interposing relay panel and whether it's still required in modern system?
