Your advantages in detail

Maximum explosion protection for all Ex zones and gas groups

Ex and IECEx approvals

MACX Analog Ex signal conditioners are approved in accordance with the applicable standards.

All MACX Analog Ex signal conditioners are approved in accordance with the applicable ATEX and 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 national approvals such as UL and GOST are available.

Significant space savings

Comparison of design widths  

Up to 45% space saving with MACX Analog Ex

All single and two-channel 24 V devices in the MACX Analog Ex range feature a housing width of just 12.5 mm. This saves up to 45% space compared to other Ex i signal conditioners on the market.

Safe and reliable functions

SIL logo  

MACX Analog Ex signal conditioners are all consistently SIL-certified according to IEC 61508

Phoenix Contact meets the requirements of functional safety according to IEC 61508 in a standardized development process.

The certified MACX Analog Ex signal conditioners are available in all safety-related applications up to SIL 2 or SIL 3. This ensures the highest level of reliability and safety for your systems.

In addition, patented circuit concepts ensure precise transmission and low current consumption. The resulting minimal self-heating results in a long service life for devices.

Precise signal transmission with low power dissipation

Self-heating on a thermal image  

Low self-heating results in a long service life

Patented circuit concepts ensure low current consumption. The resulting self-heating results in a long service life for devices.

High operational reliability

Safe electrical isolation of input, output, and supply  

High operational reliability, thanks to 3-way electrical isolation

MACX Analog Ex signal conditioners are consistently designed with safe electrical isolation between input, output, and supply. This increases operational reliability in the event of disturbances in your system.

Intelligent concept for supply and diagnostics

Supply via DIN rail connector  

Modular bridging of 24 V supply and diagnostics signals

MACX Analog Ex signal conditioners offer two solutions for the device supply:

The system solution
Bridge the 24 V supply voltage using the DIN rail connector. This simplifies wiring, system expansion or module replacement. You can therefore either supply the supply voltage directly via any MACX Analog Ex module or use the power and error message module. In addition to easy power supply, this also offers a redundant supply decoupled from the diode plus the option of error indication.

The flexible solution
Thanks to the wide-range power supply, you can install appropriately equipped MACX Analog signal conditioners directly in all power supply networks – worldwide and without an additional power supply unit.

Convenient configuration and monitoring

IFS-CONF system software  

Convenient configuration and monitoring via software

Compatible MACX Analog Ex signal conditioners can also be configured easily from the PC using the free software.

Here you can choose between three solutions:

  1. ANALOG-CONF stand-alone software
  2. FDT/DTM software package
  3. Stand-alone DTMs, allowing you to use your existing FDT frame application

The integrated monitoring function enables you to record current system values. All devices that support configuration via software can also be supplied preconfigured on request.

Easy configuration also possible without software

Configuration via DIP switches  

MACX Analog Ex can be configured quickly and easily via DIP switches.

MACX Analog Ex signal conditioners can be configured very easily without software. You can choose from various configuration methods according to the device type:

  • Via DIP switches, directly under the transparent cover on the front of the device.
  • Via operator interface and display unit, which are simply snapped onto compatible devices. You can therefore also copy your settings onto other modules or monitor process values directly in the control cabinet.
    When used in combination with the separate holder, you have a convenient hand-held operator panel that can also be mounted on a DIN rail as a remote display unit.

For easy-maintenance mounting: plug-in connection terminal blocks

Plug-in connection terminal blocks  

Plug-in connection terminal blocks with coding

MACX Analog Ex signal conditioners are equipped with plug-in connection terminal blocks. You can choose between screw technology or a spring-cage version with push-in technology.

Coding and clear marking ensure reliable protection against polarity reversal and prevent unintentional mismatching of pre-wired connection terminal blocks.

In addition, we have integrated sockets into the connection terminal blocks. They can be used to connect your HART communicators, for example.

Fast and error-free signal connection

Termination carriers with MACX Analog Ex signal conditioners  

MACX Analog Ex termination carriers with standard DIN rail devices

Termination carriers are compact solutions for quickly and smoothly connecting DIN rail devices from the MACX Analog Ex series to input and output cards of automation systems.

Connect the termination carriers to your controller quickly and smoothly using pre-assembled VARIOFACE system cabling – plug and play.

You can therefore combine the advantages of modular DIN rail devices with those offered by plug and play system cabling to create a consistent solution for system technology.
