Highly compact and leading technology: with an overall width of just 12.5 mm, MACX Analog Ex offers single and two-channel signal isolators for Ex i circuits. The products are type-tested by an independent NAMUR test laboratory in accordance with NE 95 and therefore satisfy the high requirements of the chemical industry.

Your advantages

  • Universal use for intrinsically safe circuits in all Ex zones and for all gas and dust groups, thanks to international approval package
  • Functional safety and reliability with consistent SIL certification
  • Significant space savings with an overall width of just 12.5 mm for all single and two-channel 24 V devices
  • Precise, interference-free signal transmission, thanks to a patented transmission concept with safe electrical isolation and low self-heating
  • Convenient configuration and monitoring: via DIP switches and operator interface or with software for extended functionality and monitoring
  • Easy installation and startup, thanks to plug-in connection terminal blocks, easy configuration, and consistent system cabling solution with Termination Carrier
  • Flexible energy supply: versions with wide-range input or 24 V versions with easy power bridging via the modular DIN rail connector

MACX Analog Ex – maximum explosion protection for all Ex zones and groups

MACX Analog Ex signal conditioners with comprehensive approval package

Many process technology systems have areas where potentially explosive atmospheres may occur. As such, measuring and control circuits are designed with intrinsic safety protection type Ex i.

MACX Analog Ex i signal conditioners and measuring transducers isolate intrinsically safe circuits from non-intrinsically safe circuits and safely limit the energy supplied to the hazardous area. Furthermore, they handle extensive signal conditioning tasks.

All MACX Analog Ex signal conditioners are approved in accordance with the applicable ATEX/IECEx standards:

  • [Ex ia]: for intrinsically safe circuits up to Ex zone 0 and Ex zone 20
  • Ex n: for installing devices in Ex zone 2

In addition, relevant international approvals such as UL and EAC are available.
