AC Control / DC Load
Delcon Solid State Relays - Ex Relays Series AC Control / DC Load
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
