LED modules 24 V for intrinsic safety (front plate mounting)
LED modules for front plate mounting are installed on the rear face of a holder. The LED
modules are approved in accordance with IEC 60079-11 and are used in hazardous zones
1, 2. They comply with the "ib" type of protection for intrinsic safety.
● [ATEX] II 2G Ex ib IIC T4 Gb
● Type of protection: ib (= intrinsically safe, Zone 1)
● Hazardous areas IIC subject to gas explosion (hydrogen)
● Device category EPL: Gb
● Temperature class: T4
Input variables compliant with IEC 60079-11:
● U
i
= 28.8 V DC
● U
