The new NOARK® Electric Ex9RCA Safety Control Relay is designed to provide fail-safe performance for safety function applications. It features mechanically linked contacts for use on safety feedback circuits with up to 8 contacts. When installed the normally closed contact is force guided with the normally open contacts making the Ex9RCA ideal for SRP/CS (SRP/CS is the term given by ISO short for safety-related part of a control system, meaning part of a control system that responds to safety-related input signals and generates safety-related output signals).
