Addressed (FDnet-Ex/C-NET-Ex) For operating
FDnet-Ex/C-NET-Ex peripheral devices in areas at risk of explosion
Electrical isolation between non-intrinsically safe and intrinsically safe circuits
Use on FDnet/C-NET detector lines, on stubs, or loops
Status indicator/operating indicator with two LEDs
MC link connection
Installation in fire control panels or in an installation housing FDCH222
Features
Protected electronics
Integrated operating indicator
Integrated LED for signaling the isolation of the area at risk of explosion
Eco-friendly
Environmentally friendly processing
Reusable materials
Electronic parts and synthetic materials can be separated
The line adapter (Ex) is used for electrical isolation purposes and for limiting the electrical energy between non-intrinsically safe and intrinsically safe circuits.
It is not necessary for the housing to be connected to local ground
The power required for the line adapter (Ex) to supply itself is taken from the FDnet/CNET.
It is not necessary to connect an external power supply Operation possible on an FDnet/C-NET detector line or a stub.
There is therefore no line separation function in the area not at risk.
The line adapter (Ex) has two connections for the detector line (FDnet/C-NET) in the area not at risk and
one connection in the area at risk of explosion (FDnet-Ex/C-NETEx).
Two LEDs for displaying the operating status and faults, and for localizing the device
