Relays for hazardous locations with AC input ("coil") voltage and DC load voltage

Main benefits comparing to electromechanical relays and opto-coupled relays:

- No limited lifetime, 7 to 10 year warranty time depending on relay type
- High tolerance against noises
- Guaranteed switching on and off -levels
- 100 % clear status indication
- Relatively high transient protection
- Extreme reliability
- No minimum load requirement
