Inherent Safety And Explosion-Proof Construction
Contact signal converter (Barrier relay)
Authorized product by the official approval
By sending the open/close signal from the pressure switch throughthis barrier relay, the pressure switches (excluding the electronictype) can be applied safely and intrinsically even in the hazardous
area of Division 0, 1 and 2 areas where the explosive gases exist.
Explosion-proof capacity: i3nG5
Applicable gases:
Less than Explosion Class 3,
Ignition Group 5 Can be used forhydrogen, acetylene and carbon
disulfide
Model:
IBR2011 AC100V 1 contact
IBR2021 AC100V 2 contacts
