MACX Analog Ex signal conditioners are 12.5 mm wide, include one or two channels with SIL reliability data, and link control and field devices in EX and non-EX locations. MACX can serve as a safe power limitation in IS circuits in potentially explosive areas, up to Class I, Div. 1 and Zone 0. Due to SIL calculations, according to EN 61508-1, they can be designed into safety-related applications.
