The MACX Analog Ex-i isolation amplifiers from Phoenix Contact have successfully passed type testing in accordance with NAMUR NA 95. This means the devices meet the requirements of the Industrial Practices Interest Group (IGR), an association of the chemical and pharmaceutical industries.
Isolation amplifiers are single- and dual-channel signal isolators for intrinsically safe circuits in potentially explosive areas. These products deliver maximum system safety and explosion protection with minimal space requirements. The slim 12,5 mm modules offer a wide range of features and come with ATEX and IECEx approval and full SIL certification.
NAMUR NE 95 encompasses both the testing of technical properties and the analysis of aspects such as explosion protection, maintenance and repairs, installation and device documentation. The test reports certify that the devices deliver excellent technical properties in terms of precision and ambient temperature influence; offer electromagnetic compatibility as per NAMUR NE 21; are fully compatible with Ex-i field devices; have clear and easy-to-understand documentation; and make good use of space.
IGR is the knowledge platform of the chemical and pharmaceutical industry. It has 31 member companies ranging from AkzoNobel to Weylchemie. It promotes the exchange of information and experience regarding the complete lifecycle of plants and systems. IGR also provides services such as the monitoring of relevant regulations and the assurance of quality standards.
