About the Product

Product Introduction

The MTL4015 is a single-channel interface that connects hazardous-area sensors to two independent safe-area systems. Ideal for critical applications requiring dual signaling (e.g., control + shutdown systems).

Key Features

  • Dual relay outputs for redundant system integration
  • Phase-reversal switch for alarm state configuration
  • Built-in Line Fault Detection (LFD) for broken/short circuits
  • Optional earth fault protection via MTL4220
  • Compliant with NAMUR/DIN 19234 standards

Technical Specifications

  • Input: 7.0–9.0V DC via 1kΩ
  • Thresholds: 2.1mA (activate) | 1.2mA (deactivate)
  • LFD Range: <100µA (open) | >6.5mA (short)
  • Relays: 2× 10W/0.5A, 2ms response
  • Power: 20–35V DC, 45–60mA
  • Isolation: 250V AC
  • Weight:0.15kg

Applications

Essential for oil/gas shutdown systems, chemical plant controls, and other safety-critical dual-signaling applications in explosive atmospheres.

Safety Note: Switch-type sensors require external resistors to prevent LFD false triggers. Phase reversal allows alarm customization for NO/NC sensors.
