Intrinsically Safe Explosion-proof
EB3N Safety Relay Barrier
First ever in the world! Safety relay barrier rated by Japan TIIS ([Exia] II C) and
Machine Safety Standard ISO 13849-1 (PLe, Cat 4)
Ensures machine safety in an explosive atmosphere
EB3N ensures explosion protection safety and machine safety

Machine Safety
By combining the EB3N safety relay barrier with safety input devices, such as emergency stop switches or interlock switches,
and contactors compliant with safety standards, explosion protection safety and machine safety can be achieved. In addition,
safety control devices, such as safety relay modules or safety controllers, can also be combined to build a safety system.
Conventional system does not ensure machine safety

Combining a conventional contact signal transducer with safety input devices, such as emergency stop switches or interlock
switches, and safety control devices such as safety relay modules, safety controllers, or safety PLCs will also meet explosion
protection safety, but does not meet machine safety.
