Relays for hazardous locations with DC input (control) voltage and DC load voltage.
EXI-relays for mA-size loads and EXO-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
