Brief: Wondering how the MTL 5517 HART Repeater extends communication in hazardous areas? This video provides a detailed walkthrough of its dual-channel signal regeneration capabilities. You'll see how it boosts and maintains signal integrity for 4-20mA+HART communication over long distances, with demonstrations of its DIN rail mounting and configuration process for industrial applications.
Related Product Features:
  • Dual-channel HART signal repeater that regenerates and amplifies weakened 4-20mA+HART signals for extended transmission.
  • Extends HART network communication distance up to 3,000 meters while maintaining complete signal integrity.
  • Provides 500V AC galvanic isolation between field and safe areas for enhanced safety in hazardous locations.
  • Certified for Zone 1, IIC, T6 hazardous areas with ATEX, IECEx, FM, CSA, and NEPSI approvals.
  • Maintains high analog accuracy of ±0.05% of span while preserving bidirectional HART digital data.
  • Features transparent operation that passes HART protocol unchanged without requiring device addressing.
  • Includes visual diagnostics with bi-color LED indicators for power status and HART communication activity.
  • Software-configurable via PC for setting fail-safe modes and other operational parameters.
FAQs:
  • What is the maximum distance the MTL 5517 can extend HART communication?
    The MTL 5517 HART Repeater can extend HART communication up to 3,000 meters when used with appropriate cable, overcoming signal degradation in long cable runs.
  • Is the MTL 5517 certified for use in hazardous locations?
    Yes, the MTL 5517 is certified for Zone 1, IIC, T6 (Gas) and A21, T85°C (Dust) hazardous areas with ATEX, IECEx, FM, CSA, and NEPSI approvals for intrinsically safe applications.
  • How is the MTL 5517 HART Repeater configured and what power does it require?
    The MTL 5517 is configured via PC software using a USB cable and requires an external 20-30V DC power supply (24V typical) for operation, while field devices need separate loop power from an IS power supply.
  • Does the MTL 5517 maintain both analog and digital signal accuracy?
    Yes, the MTL 5517 provides complete signal integrity with ±0.05% analog accuracy and maintains bidirectional HART digital data through full signal regeneration.
