About the Product

Hazardous Area Switch Interface

The MTL3011 safely connects hazardous-area proximity detectors or switches to safe-area control systems. Featuring a relay output and intelligent fault detection, it provides reliable operation in critical safety applications.

Key Features

  • Built-in line-fault detection for broken/short-circuited wiring
  • Configurable phase-reverse control for alarm condition setting
  • Compliant with NAMUR/DIN 19234 proximity detector standards
  • Visual LED status indicator for output state monitoring
  • Universal 7.7-9V DC sensor supply from 1kΩ source

Technical Specifications

Certification
Zone 0, IIC, T6 (Switch)
Zone 0, IIC, T4-6 (Proximity)

Input Thresholds
>2.1mA (Closed output)
<1.2mA (Open output)

Response Time
1ms typical

Relay Rating
200V, 0.5A (10VA/W)

Application Notes

For switch-type sensors, either:

  1. Add external resistors to emulate proximity detectors, or
  2. Disable line-fault detection via terminals 7-8 link

Reactive loads require proper suppression to protect relay contacts.
