The product line is divided into three functional groups. The “Intrinsically safe signal converter for C&I signals at the Ex zone” group includes eight different variants with an overall width of 22.5mm and high-grade 3-way isolation that can process all standard input signals 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 of the process. The modules are ATEX certified and available in 1- or 2-channel versions. The second group of devices, the “Signal converter/isolator for analogue signals housed in compact mounting form”, includes 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 a to 10V industrial signals.

The precise measurements and the wide temperature range enable many different industrial applications. The units come in a space-saving 6mm wide mounting form. With the third group of devices dubbed “Universal converter for digital signal conditioning with HART communication”, Müller Industrie-Elektronik offers diverse universal converter for digital signal conditioning with 4 to 20mA HART output and wide alternatives of configuration.

The modules 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. More options are 1, 2 or 4 channel versions, radio technology and mounting forms in 6, 12.5, 22.5 and 45.5mm width for mounting in electrical cabinet.
