MTL 5011B Blower Fan: 6500RPM High Speed, 16dB Ultra-Quiet, 50K Hrs for Electronics

ATEX/IECEx-Certified Single-Channel Interface for Hazardous Area Switch Monitoring

The MTL5011B is a compact, single-channel interface module designed for seamless integration with NAMUR-compliant switches or proximity detectors in Zone 0/IIC/T6 hazardous environments. Certified to ATEX Directive 2014/34/EU (EEx ia IIC, Certificate BAS 01 ATEX 7147) and IECEx (BAS 05.0063), it ensures safe operation by limiting energy to 10.5V/800Ω/14mA while supporting Um=250V rms/dc for high-voltage applications.

Its advanced line fault detection (LFD) continuously monitors open/short circuits in field wiring, triggering relay deactivation and front-panel LED alerts for immediate diagnostics. The user-selectable phase reversal control allows alarm configuration for both sensor states (normal/actuated), offering flexibility unmatched by competitor solutions like P+F's KFD2-SH-EX1, which lacks dynamic state customization.

Built to withstand harsh operational environments, the MTL5011B features a galvanically isolated design and IP65-rated enclosure (derived from MTL's 5000 series legacy) to protect against dust, water ingress, and corrosive gases. Operating flawlessly across -20°C to +60°C, it outperforms P+F's KFD2-SH-EX1, which has a narrower temperature range of -10°C to +55°C.

The solid-state relay outputs (250V AC/2A resistive load) eliminate mechanical wear, ensuring a lifespan exceeding 100,000 cycles--a critical advantage in high-frequency applications. With low power consumption (35mA at 24V DC) and EMC compliance, the module minimizes heat dissipation and interference in electrically noisy settings.

The MTL5011B redefines modularity with its plug-and-play architecture, enabling quick retrofitting into existing DCS/PLC systems. Its floating relay outputs support direct connection to logic circuits without additional signal conditioning, reducing setup complexity compared to Siemens' similar modules.

For scalable applications, the module can be daisy-chained using MTL's power bus system, simplifying power distribution and cutting cabling costs by 20%. Unlike Phoenix Contact's safety barriers, which require external configuration tools, the MTL5011B's intuitive top-mounted switches allow on-site adjustments for phase reversal and LFD thresholds, minimizing commissioning time.
