Newson Gale has launched its next generation static grounding relay, the Earth-Rite® OMEGA II. Featuring ATEX, IECEx and cCSAus Intrinsically Safe certified circuits for the highest gas, vapour and dust groups the Earth-Rite® OMEGA II monitors the resistance of circuits designed to ground equipment that are subjected to electrostatic charging.
The new DIN rail mountable relay caters for installations where dedicated grounding systems like the Earth-Rite® RTR or Earth-Rite® PLUS would not normally form part of an electrical contractor’s turnkey control panel project for an EX hazardous area installation.
The Earth-Rite® OMEGA II features four adjustable resistance monitoring settings that can cater for the specific requirements of a wide range of static grounding applications. The resistance monitoring settings available for selection are 2 ohms, 4 ohms, 10 ohms and 600 ohms. By ensuring the grounding circuit has a low resistance path to a verified earth ground, the risk of an ignition caused by an electrostatic discharge is controlled to safe levels.
The Earth-Rite® OMEGA II relay has a certified operating temperature range of -40° C to +60° C (-40° F to +140° F) and carries SIL 2 certification in accordance with the requirements of IEC 61508. It requires a 24 V DC power supply with up to four relays powered simultaneously by a single power supply. The relays are normally mounted in the non-hazardous area but can be mounted in a suitably certified Ex(d) flameproof enclosure located in the hazardous area.
