DC Control / DC Load
Delcon Solid State Relays - SL Relays Series DC Control / DC Load
Relays with DC input ("coil") voltage and DC load voltage.
SLI-relays for mA-size loads and SLO-relays for Ampere-size loads.
Main benefits comparing to electromechanical relays and opto coupled relays:
• No limited lifetime even with difficult loads, 10 year warranty
• High tolerance against noises
• Guaranteed switching on- and off-levels
• 100 % clear status indication
• Relatively high transient protection
• Extreme reliability
• No need for over dimension of the relay, all values are effective values
• Special relay types for inductive and high DC-loads, no need for extra protection elements
• No minimum load requirement
