Electrical safety (for hazardous-area use)
Intrinsic safety: Non-energy storing apparatus (<1.2V,<0.1A, <20μJ, <25mW), Ceq=0, Leq=0; the device can be connected into any IS loop with input power< 2W.
Flameproof/Explosionproof: No effect on existing Ex d approval when fi tted into an STT350 transmitter in an approved housing.
