Müller Industrie-Elektronik offers a wide range of compact DIN rail mount electronic modules to provide solutions for transmission, conversion, controlling, and communication of signals in industrial applications, including those found in potentially explosive atmospheres. The product line can be divided into three groups. The intrinsically safe ATEX approved signal converters for control and instrumentation signals in Ex zones have eight variants with 22.5 mm overall width and high-grade 3-way isolation. They can process all standard input signal such as 2-wire, HART, NAMUR, RTD, thermocouple or DC from the Ex zone 0 as well as digital or analogue signals from Ex-zone for field devices to the controller. The integrated relay output issues an alert in the event of a malfunction and provides a quick fault analysis at the process. As an option these modules are available as 1- or 2-channel versions.The second group comprises the signal converter/isolator for analogue signals housed in compact mounting form. These include a universal converter, 1 or 2 channel passive isolators, a universal DC converter and a signal multiplier. The devices act as galvanic isolator and converter for 0 to 20mA, 4 to 20mA and 0 to 10 V industrial signals and enhance process reliability. The precise measurements and the wide temperature range enable many different industrial applications. The compact mounting form in 6 mm width saves space in the electrical cabinet. The universal converter, in the third group, with 4 to 20 mA HART output is suitable for digital signal conditioning. It can process input signals such as strain gauge, DC current/voltage, resistance thermometer, thermocouple and potentiometer. For data analysis a 4 digit display can be integrated in some modules. Additional options include 1, 2 or 4 channel versions, radio technology and mounting forms in 6 mm, 12.5 mm, 22.5 and 45.5 mm width for mounting in electrical cabinet.
