وصف المنتج

1. Intrinsic Safety Barrier Solution

The Honeywell MTL24571 is a galvanically isolated intrinsic safety (IS) barrier engineered for hazardous area signal conditioning in Zone 0/20 explosive atmospheres. Featuring ​Ex ia IIC T4 certification, this device provides ​250V AC/DC isolation​ between safe and hazardous areas while supporting ​4-20mA analog signals​ with ​​≤0.01% linearity error. Its ​robust epoxy-potted enclosure​ offers ​IP20 protection​ and withstands ​​-40°C to +80°C​ operating temperatures. The barrier incorporates ​fault-tolerant Zener diode technology​ with ​current limiting ≤93mA​ and ​voltage clamping ≤30V DC​ to prevent ignition-capable energy transmission. Certified for ​ATEX/IECEx/FM/CSA, it enables SIL 2 safety loop compliance (IEC 61508) with ​galvanic separation​ up to ​1500V AC. Designed for transmitters, solenoid valves, and sensors in oil/gas, chemical, and pharmaceutical industries, this barrier ensures safe signal transmission in explosive gas/dust environments without requiring external isolators.

2. Critical Technical Specifications

Key parameters include ​2-wire loop support​ with ​24V DC supply​ (18-30V range), ​100Ω maximum loop resistance, and ​1.5W power dissipation. The barrier achieves ​​±0.05% accuracy​ at 20mA with ​​<10ppm/°C thermal drift. Electrical isolation ratings include ​1500V AC test voltage​ (input-output) and ​500V AC​ (input-ground). Connection utilizes ​screw terminals​ (0.5-2.5mm²) with ​color-coded channels​ (blue=safe, yellow=hazardous). Certifications cover ​ATEX Ex ia IIC T4 Ga, ​IECEx Ex ia IIC T4 Gb, ​FM/CSA Cl I Div 1, and ​SIL 2​ (PFHD 1×10⁻⁸/h). Dimensions are ​22.5×110×115mm​ (W×H×D) with ​DIN-rail mounting​ (EN 60715). Environmental compliance includes ​EN 60068-2 vibration resistance​ (15g) and ​IEC 60079-0 impact protection​ (7J).

3. Hazardous Area Applications

This barrier excels in explosive environment scenarios:

  • Oil & Gas Wellheads: Pressure transmitter isolation in Zone 0
  • Chemical Reactors: Temperature sensor protection (Zone 1/21)
  • Pharmaceutical: Solenoid valve control in solvent zones (Zone 1)
  • Grain Silos: Level sensor safety in combustible dust (Zone 20)
  • Paint Spray Booths: VOC concentration monitoring
  • Methane Detection: Gas sensor circuits in coal mines
  • Tank Farms: Overfill prevention system isolation
  • Hydrogen Fueling: Leak detection in refueling stations
    Its Ex ia IIC T4 certification allows installation in hydrogen environments (Group IIC), while the SIL 2 rating supports safety instrumented functions (SIF) for applications like emergency depressurization systems. The epoxy encapsulation resists corrosive chemicals in offshore installations and maintains performance during thermal cycling from -40°C to +80°C.

4. Functional Safety Advantages

  • Explosion Protection:
    Triple-redundant Zener barriers with current/voltage clamping
    <30V/93mA output limits prevent ignition energy
  • Signal Integrity:
    ±0.05% accuracy with EMI immunity >150dB
    Galvanic isolation eliminates ground loops
  • Diagnostic Capability:
    Visual LED status (green=power, red=fault)
    Loop resistance monitoring via test points
  • Installation Efficiency:
    Tool-less DIN-rail clip (EN 60715)
    Terminal markings per IEC 60947-7
  • Compliance Coverage:
    Global certifications (ATEX/IECEx/FM/CSA)
    SIL 2 hardware fault tolerance
  • Lifecycle Durability:
    20-year service life
    Hermetic epoxy seal prevents moisture ingress

5. Safety Operation & Integration

Protection Mechanism:

  1. Voltage Clamping:
    Zener diodes limit hazardous-side voltage ≤30V DC
  2. Current Limiting:
    Resistor-fuse network caps current ≤93mA
  3. Isolation Barrier:
    Transformer separation withstands 1500V AC

Diagnostic & Maintenance:

LED State Status Action
Solid Green Normal None
Flashing Green Marginal Check loop
Solid Red Fault Replace
Testing Protocol:    
  • Annual loop resistance verification (≤100Ω)
  • 5-year dielectric strength test (1500V AC)
  • SIL verification via Honeywell Safety Manager Suite
