Technical Information Application The ia safety barrier type 145 is used in conjunction with a non-Ex-approved signal conditioning instrument for intrinsically and galvanically isolated supply at Ex-approved electrodes or Ex-approved pressure sensors in hazardous areas and for signal transmission. Attention: Safety barrier and signal conditioning instrument must not be installed in the hazardous area.
Technical Information Technical data Input Output Input voltage from the signal conditioning instrument 22 … 24 V DC Input current 4 … 20 mA Output voltage to the transducer (dependent on sensor current) 12 … 16 V Output circuit (intrinsically) 4 … 20 mA Flame proofing intrinsic safety Max. values Umax. IK Pmax. Max. permissible outer inductance Max. permissible outer capacitance Max.
