MTL 5015 Intrinsic Safety Barrier ATEX IECEx Certified For Hazardous Area Control

The MTL 5015, a dual-channel solid-state switch/proximity detector interface from the MTL 5000 series, is engineered to deliver reliable signal isolation in explosive atmospheres. Designed for Zone 0/20 hazardous areas, this module ensures safe operation by limiting energy transfer to intrinsically safe levels, complying with FM certification (FM 3600:1989) and European directives for intrinsic safety.

It features a 35 VDC input with 7-9 VDC sensor excitation and 10.5 VDC safety voltage, supporting NAMUR-standard proximity detectors with line fault detection (LFD) and phase reversal capabilities. The module's compact 16 mm width and plug-in DIN rail mounting enable space-efficient installations, while its 10 ms maximum response time ensures rapid signal processing. Unlike traditional relays, the solid-state design reduces wear and tear, enhancing longevity in harsh industrial settings. Ideal for applications requiring high precision and fail-safe operation, the MTL 5015 is a cornerstone for safety-critical systems in petrochemical, pharmaceutical, and offshore industries.

The MTL 5015 stands out for its integrated diagnostic features that streamline maintenance and reduce downtime. Its LFD function detects open/short circuits in field wiring, triggering an LED alarm and de-energizing the output to prevent false signals. Users can configure LFD thresholds via onboard switches, adapting to specific sensor requirements.

The phase reversal control allows alarm signaling for both normal and reversed sensor states, providing flexibility in system design. With 3-port galvanic isolation and low power dissipation, the module minimizes electromagnetic interference while ensuring signal integrity. Compared to competitors like Pepperl+Fuchs' safety barriers, the MTL 5015 offers a more intuitive interface and faster fault detection, making it preferable for complex industrial networks. Additionally, its compatibility with MTL's PCL 45 USB configurator enables remote parameter adjustment from a safe area, optimizing operational efficiency.
