1. Dual-Channel Intrinsically Safe Repeater Power Supply for Hazardous Environments

The MTL4044D is a high-reliability dual-channel repeater power supply designed for 2-wire 4–20mA transmitters in ATEX/IECEx-certified Zone 0/1/2 hazardous areas (EEx ia IIC T4-T6). Unlike Phoenix Contact’s ILC 1710-SF-UI, which lacks intrinsic safety certification for Zone 0, the MTL4044D ensures safe operation in explosive gas environments while providing 250V AC galvanic isolation between field and safe-area circuits. Its one-input, two-output design supports simultaneous power and signal transmission to two separate devices (e.g., PLCs, recorders), reducing panel space by 30% in petrochemical plants compared to single-channel solutions. With a 116.6mA maximum output current and 800Ω load capacity, it outperforms Pepperl+Fuchs’ KFD2-SR2-EX1.D in high-power applications like pressure transmitters in offshore platforms. The module’s screwless terminals enable rapid wiring, while its 110g lightweight design enhances portability in field installations.

2. Precision Signal Conditioning with HART-Enabled Smart Device Integration

Featuring HART protocol overlay via FSK modulation, the MTL4044D supports remote configuration and diagnostics for smart transmitters, a capability absent in ABB’s S200 series. Its ±0.1% signal accuracy and 200µA hysteresis ensure stable operation in noisy environments, activating outputs at >2.1mA and deactivating below 1.2mA. While Pepperl+Fuchs’ KFD2-HM-16 supports multi-drop HART devices, the MTL4044D’s single-device-per-channel design simplifies troubleshooting and minimizes signal interference in critical systems like wastewater treatment plants. The module’s loop-powered design (20–35V DC) reduces energy consumption by 15% compared to standalone power supplies, with a 1.2W power dissipation at 24V DC. For retrofitting legacy systems, its plug-and-play compatibility with MTL4000-series backplanes ensures seamless integration with Emerson DeltaV or Schneider Modicon control systems.

3. Rugged Durability and Versatile Compatibility for Harsh Industrial Settings

Built for extreme conditions, the MTL4044D withstands -20°C to +60°C temperatures and IP66 ingress protection, making it suitable for outdoor applications in mining and offshore platforms. Its 17.5mm width and DIN-rail mounting optimize panel space, while the 25-year operational lifespan (with proper maintenance) reduces lifecycle costs in critical infrastructure sectors. Though discontinued, it remains a cost-effective choice for maintaining older installations, with replacements like the MTL4541B offering enhanced diagnostics and SIL2 certification. The module’s selectable phase reversal via side-mounted switches accommodates diverse transmitter configurations, outperforming Yokogawa’s DPharp EJX series in adaptability. For safety-critical environments, its ATEX/IECEx certification (II (I) GD BAS 99 ATEX 7061) ensures compliance with global explosion-proof standards. This combination of safety, precision, and durability solidifies its role as a trusted solution for hazardous area automation.
