| | | The Series N-131... isolating switching amplifiers transmit switching operations from an intrinsically safe control circuit to a non-intrinsically safe active current circuit. The control units are designed according to NAMUR-DIN 19234 or EN 60947-5-6 intrinsically safe and according to EN 50014 and EN 50020 [EExia] II C. The conformity is certified in Germany by TUV-NORD. Power pack, switching amplifier, electronic evaluation unit and output relay are all integrated in the 22 mm sized housing. The units are EMV-approved according to IEC 801-2 to 5. Quick mounting is possible on profile according to DIN 46 277. Led displays are integrated in the front plate for stand-by (green), state of output (yellow) and wire-break/shortcircuit of the sensor cable (red). The isolating switching amplifiers can be actuated by NAMUR sensors, e.g. our series IAS-30... and KAS-40..., or by mechanical contacts. | | |
