Product Specification

Dual-Channel Intrinsic Safety Repeater Power Supply for Hazardous Zones

The MTL 5044 is a high-reliability industrial automation component engineered to deliver precision signal conditioning in explosive environments. As a dual-channel intrinsic safety repeater power supply, it provides isolated 4-20 mA signal transmission for two 2-wire transmitters in Zone 0/IIC hazardous areas, outperforming traditional single-channel solutions like the MTL 5042 . Its advanced galvanic isolation technology ensures 250 V rms isolation between input, output, and power terminals, effectively eliminating ground loops and electromagnetic interference. With ±5 µA typical conversion accuracy at 20°C and a rapid 250 µs response time, the 5044 excels in dynamic process control scenarios, surpassing competitors like Pepperl+Fuchs’ KFD2-SR2-EX2 in both speed and precision . The device supports bidirectional HART communication for smart transmitters (2-wire only), enabling remote configuration without compromising safety—a feature absent in many legacy systems .

Certified Ruggedness for Extreme Industrial Conditions

Built to withstand harsh industrial environments, the MTL 5044 holds comprehensive safety certifications, including ATEX (II 1 GD Ex ia IIC T4-T6), IECEx, and UL Class I, Div. 1 listings, making it suitable for oil & gas refineries, chemical plants, and pharmaceutical production facilities . Its intrinsic safety parameters (Uo = 28 V, Io = 93 mA, Po = 0.65 W) ensure compliance with global explosion protection standards, while a reinforced housing resists vibrations, 5-95% humidity, and extreme temperatures (-20°C to +60°C) . Unlike Siemens’ SICL modules, which often require additional surge protection, the MTL 5044 integrates a fail-safe mechanism that maintains signal integrity during power fluctuations, reducing downtime by up to 30% in critical applications . The compact 110g DIN rail mount design (110 x 104 x 16.2 mm) maximizes panel space, while plug-and-play terminals simplify installation and maintenance .

Scalable Integration for Modern Process Automation

The MTL 5044 redefines flexibility in industrial networks, supporting both 2-wire and 3-wire transmitters with floating output design (0-550 Ω load resistance) and seamless integration with PLCs, DCS systems, and HMIs . Its dual-channel architecture allows simultaneous signal conditioning for multiple sensors, ideal for redundant monitoring in safety-critical processes. For HART-enabled setups, the 5044 acts as a passive repeater, ensuring uninterrupted communication without external power boosters—a key advantage over Pepperl+Fuchs’ KFD2-UT2-EX1 . While superseded by the MTL5544 for new installations, the 5044 remains a cost-effective choice for legacy systems, offering backward compatibility with MTL 5000 series modules and a 10-year operational lifespan . Its low power consumption (1.5 W at 24 VDC) aligns with energy-efficient practices, while the isolated power supply design minimizes cross-channel interference . This combination of safety, scalability, and reliability positions the MTL 5044 as a cornerstone for hazardous area automation.
