The 6DR5126-.....-.... is a SIPART PS2 smart electropneumatic positioner accepting a 4-20 mA HART input, configured for double-acting actuators. It carries a flameproof (Ex d) stainless steel enclosure and uses non-contacting position sensing (NCS) — wear-free feedback for linear and part-turn pneumatic actuators. The Ex d rating means the enclosure contains any internal ignition, so it is suitable for Zone 1 gas groups without an external flame path seal.
RoHS compliant since 31 Dec 2016. No UL or IEC certificate number appears in the record; the Ex d certification is implicit in the flameproof enclosure designation but the specific standard (IEC 60079-1 or ATEX) is not itemised here. For a procurement file, request the manufacturer's declaration of conformity for the exact variant.
