The 9174 series compact electronic relay module allows Ex e loads to be switched by an intrinsically safe control system. This complements the action of intrinsically safe binary outputs, e.g. in a remote I/O system. The electronic switch prevents mechanical wear, extending the life of the relay, particularly where frequent switching operations are concerned.
- Low space requirements – 12 mm in width
- long-life module thanks to maintenance-free electronic switching: Ideal for frequent switching operations
- for installation in Zone1, especially in combination with remote I/O systems
