OPTIFLUX INTRODUCTION 1 1.5 OPTIFLUX 5000 1.5.1 Compact versions OPTIFLUX 5300 C is certified as group II, category 2 GD equipment if fitted with an IFC 300 signal converter without Ex ia signal in/outputs or as a group II, category 2 (1) GD equipment, if fitted with a signal converter with Ex ia signal in/outputs. It is therefore suitable for installation in gas hazardous areas zone 1 and 2, gas group IIC, temperature class T6…T3 and dust hazardous areas zone 21 or zone 22, surface temperature T85...180°C. Additionally, the Ex ia signal in/outputs of the signal converter may run or originate from a Zone 0 gas hazardous area. The sensor is available in "sandwich" and in "flange" version. Converter housing, connection compartment: with power supply (terminals L, N / L+, L-) and I/O connections (terminals A, A+, A-, B, B-, C, C-, D and D-): Ex e (increased safety), optionally: Ex d (Flameproof enclosure). For certain versions of the signal converter the terminals A, A+, A-, B, B-, C, C-, D and D- are additionally Ex ia (Intrinsic safety). Consult the table with CG numbers for details.
