The Series 9174 compact electronic relay module allows Ex e loads to be switched by an intrinsically safe control system. This complements 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.
- Requires little space – width of 12 mm
- Durable module thanks to maintenance-free electronic switching: Ideal for frequent switching operations
- Enables use in Zone 1
