1.5 IFC 300 F / PF

The IFC 300 F/PF is certified as group II, category 2G equipment, if fitted without Ex ia signal in/outputs or as a group II, category 2(1)G equipment, if fitted with Ex ia signal inputs/outputs. It is therefore suitable for installation in gas hazardous areas zone 1 or 2, gas group IIC, temperature class T6. Additionally, The Ex ia signal in/outputs of the converter may run or originate from a zone 0 gas hazardous area.

In the IFC 300 F / PF signal converter the following types of protections are used:

Converter housing, terminal compartment:

• Power supply (terminals L, N, PE or L+, L-), in type of protection Increased safety (Ex e): Un = 100...230 VAC or 24 VAC/DC or 12...24 VDC.

• Signal I/O (terminals A, A+, A-, B, B-, C, C-, D and D- ), in type of protection Increased safety (Ex e) or - optional - Intrinsic safety (Ex ia).

For certain versions of the signal converter the terminals A, A+, A-, B, B-, C, C-, D and D- are additionally in type of protection Intrinsic safety. Consult the table with CG numbers in the handbook of the IFC 300 for details.
