Petra Mechatronics Middle East | Authorized reseller of Dini Argeo
Kit of three intrinsic protection Zener barriers, for connection of devices in ATEX area with devices in safe area, housed in an ABS box.
Marking of single barrier: ATEX II (1) GD [Ex ia Ga] IIC [Ex ia Da] IIIC.
Marking of the whole box with three Zener barriers:
ATEX II 3(1)G Ex nA [ia Ga] IIC T4 Gc (-20°C ≤ Ta ≤ +40°C) for gas
ATEX II 3(1)D Ex tb [ia Da] IIIC T130°C Dc IP65 (-20°C ≤ Ta ≤ +40°C) for dust.
SINGLE CHANNEL FEATURES
- Barrier for signal and sense: Um=250V
Fuse: 50mA
Uo: 17,4V
Io: 25mA
Po: 0,11W
Co: 0,346µF
Lo: 56,88mH
Rmin: 705,6Ohm - Barrier for supply: Um=250V
Fuse: 100mA
Uo: 24V
Io: 164mA
Po: 0,98W
Co: 0,125µF
Lo: 1,32mH
Rmin: 147Ohm - NOTES:
– Connection with up to 4 load cells of 350 ohm each.
– The combination of two or more Zener barriers (1) GD [Ex ia] implies that the Atex marking of the barriers assembly must be update to (2) GD [Ex ib], as required by the EN 60079-14 standard.
WARNING
The KMB4 kit can be placed in ATEX zone according to its ATEX marking or in alternative in a safe area.
The electric coordination, executed for realizing the DCATEXMB4 certificate, involves the use of the LCCB/EXCB6 cable, maximum length of 200m (greater lengths upon price estimate).
Dini Argeo non Atex indicator and KMB4 box in safe area, connected to the Dini Argeo ATEX platform in hazardous area. The system is provided with declaration of ATEX conformity (code DCATEXMB4).
DFWATEX3GD Dini Argeo indicator and KMB4 box in ATEX 2 & 22 areas, connected to the Dini Argeo ATEX platform in ATEX 1 & 21 areas. The system is provided with declaration of ATEX conformity (code DCATEXMB4).
