The MACX Safety Ex analog Ex i signal conditioners are all SIL-certified and equipped with performance level PL d according to EN ISO 13849-1. The products also have ATEX and IECEx approval.

Your advantages

  • Easy integration of analog signals into the safety chain, thanks to performance level PL d
  • Universal use for intrinsically safe circuits in all Ex zones and for all gas and dust groups, thanks to international approval package
  • Cost savings: direct, safe switching of limit values possible without an additional safety controller
  • Easy planning of the safety application via SISTEMA: the required data is already stored there
  • Easy to combine active or passive analog signals with other safety modules
  • Precise, interference-free transmission and high operational reliability, thanks to a patented transmission concept with safe electrical isolation and low self-heating
  • Fast and secure installation, thanks to plug-in terminal blocks with screw connection or push-in connection technology

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

Ex /IECEx logo  

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

The MACX Safety 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.
