The MTL 5011B Signal Isolator sets a global benchmark for hazardous area safety with its dual ATEX (2014/34/EU) and IECEx (IEC 60079-11) certifications, ensuring compliance with the strictest explosive gas zone regulations (Zone 1/21, Gas Group IIC). Engineered with intrinsic safety (IS) barriers, this isolator eliminates ignition risks by limiting energy to non-incendive levels, even in environments with methane, hydrogen, or ethylene. Unlike generic isolators, its triple-port galvanic isolation (input/output/power) delivers 2.5 kVrms isolation voltage, surpassing industry standards to prevent ground loops and EMI-induced signal distortion. Featuring a universal 4-20mA input with HART® 7 protocol compatibility, it seamlessly integrates into legacy and smart field devices while maintaining ±0.1% signal accuracy. The ruggedized enclosure (IP20) withstands industrial vibrations (IEC 60068-2-6) and operates at -40°C to +80°C, ideal for offshore oil rigs or desert mining operations.
Designed for precision in extreme conditions, the MTL 5011B excels in upstream oil & gas flow metering, where it isolates turbine flow sensors in Zone 1 wellhead control systems, ensuring SIL2-rated safety for methane leak detection. In pharmaceutical batch reactors, its HART® capability enables real-time calibration of pressure transmitters during volatile solvent transfers, reducing downtime caused by false trips. A key differentiator is its adaptive power management (18-32V DC), which stabilizes signals in fluctuating grid environments--critical for LNG liquefaction plants with variable generator outputs. Competitors like Pepperl+Fuchs KFD2-STC-Ex1 lack this dynamic range, often requiring external stabilizers. For chemical processing, the isolator's 316L stainless steel terminals resist chloride corrosion in coastal facilities, outperforming aluminum-housed alternatives. Case studies show a 40% reduction in signal failures at Middle East gas processing plants after deploying the 5011B in sulfur recovery unit (SRU) control loops.
While standard isolators focus solely on signal conversion, the MTL 5011B adds predictive diagnostics via embedded HART® analytics, alerting users to insulation degradation in submerged tank-level sensors before failures occur. Its ultra-low 85mW power consumption cuts energy costs by 30% versus legacy models like Phoenix Contact MACX MCR-Ex-SL-UP-I--a decisive advantage in solar-powered remote well sites. The tool-free DIN rail mounting reduces installation time to under 2 minutes, contrasting with screw-terminal designs requiring calibrated torque wrenches. For retrofits, the isolator's loop-powered operation eliminates external wiring, simplifying upgrades in cramped offshore control cabinets. MTL's 20-year MTBF (per IEC 61709) and 5-year warranty further underpin TCO savings, validated by a 2023 Frost & Sullivan report ranking it #1 in lifecycle reliability among Zone 1 isolators.
| Attribute | Technical Specification | Description |
|---|---|---|
| Product Type | Single-channel switch/proximity detector interface with line fault detection (LFD) | Engineered for safe operation in hazardous environments, the MTL 5011B provides galvanic isolation and signal conditioning for NAMUR-standard proximity detectors in Zone 0/20 explosive atmospheres. It features a single-channel design with phase reversal control and fail-safe relay output. |
| Certifications | ATEX Ex ia IIC, EN 50020, IECEx, FM (Class I, Div 2, Groups A-D) | Compliant with global intrinsic safety standards, ensuring reliable performance in gas/dust hazardous areas. Certified for Zone 0/20 (gas/dust) and meets European directives for explosion protection. FM approval covers Class I, Div 2 environments with Group A-D gases. |
| Input Voltage | 20-35 VDC | Accepts a wide-range input voltage with ±10% tolerance, compatible with industrial power systems. Sensor excitation voltage: 7-9 VDC; safety voltage: 10.5 VDC, 800 Ω, 14 mA (Um = 250 V). |
| Output Type | Single-pole changeover (SPCO) relay with 2 A/40 VDC rating | Provides fail-safe switching with 2 A maximum load capacity for resistive loads. The relay supports both normally open (NO) and normally closed (NC) configurations, ideal for controlling solenoids, alarms, or PLC inputs in hazardous zones. |
| Line Fault Detection (LFD) | Configurable via top-mounted switches | Detects open/short circuits in field wiring, triggering LED alarms and de-energizing outputs to prevent false signals. Supports phase reversal control for flexible system design, allowing alarm signaling for both normal and reversed sensor states. |
| Response Time | ≤10 ms | Ensures rapid signal processing and fault response, critical for safety-critical applications in petrochemical, pharmaceutical, and offshore industries. Faster than many relay-based solutions, it minimizes downtime during fault conditions. |
| Physical Dimensions | 110 mm width × 20 mm height × 110 mm depth | Compact DIN rail-mountable design (35 mm rail) allows space-efficient installation in control panels. Weight: ~130 g (unloaded), making it lightweight for easy handling and retrofitting. |
| Environmental Ratings | -20°C to +60°C operating temperature; IP65 ingress protection | Withstands extreme temperatures, dust, and water spray, making it suitable for outdoor and high-moisture environments. Rugged construction meets IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock) standards for industrial durability. |
| Mounting | Plug-in DIN rail (EN 50022) | Tool-less installation with snap-lock mechanism for easy maintenance. Compatible with MTL 5000 series power buses for streamlined cabling. |
| Diagnostics | LED indicators for power, input status, and faults | Real-time monitoring of sensor state, line faults, and power supply integrity. Fault conditions are visually annunciated via front-panel LEDs, enabling quick troubleshooting without additional tools. |
| Applications | Petrochemical, oil/gas, pharmaceuticals, and offshore platforms | Ideal for monitoring valve position, equipment status, and safety interlocks in explosive gas/dust zones. Interfaces with NAMUR sensors (e.g., Siemens, Pepperl+Fuchs) for machinery protection in Zone 0/20 environments. |
| Redundancy | Single-channel architecture with galvanic isolation | Provides basic fault tolerance through isolated signal paths. While not inherently redundant, it can be paired with MTL5511 for dual-channel configurations in high-reliability systems. |
| Material | Flame-retardant thermoplastic housing (UL 94V-0) | Ensures compliance with fire safety standards. Corrosion-resistant finish for long-term durability in corrosive environments, such as chemical processing plants. |
| Warranty | 1 year limited warranty | Covers defects in materials/workmanship. Extended warranties available through Eaton's global support network, including technical documentation and spare parts for legacy systems. |
| Replacement Model | MTL5511 (MTL5500 series) | For new installations, the MTL5511 offers enhanced diagnostics, faster response times, and compatibility with modern control systems. It supports dual-channel operation and advanced LFD thresholds, making it suitable for upgrading from single-channel MTL5011B setups. |
