Description
MTL3011: Single-Channel Interface for Hazardous Area Sensors
Control a safe-area load with a switch or proximity detector in hazardous locations. The MTL3011 offers a relay output, phase-reverse control, and built-in line-fault detection (LFD) for safety. It is ideal for Zone 0 and Division 1 areas.

Frequently Asked Questions
- What sensors work with the MTL3011?
It works with NAMUR proximity detectors and switches with external resistors. - How does line-fault detection help?
LFD opens the output if wires break or short, preventing false signals. - Can I use it in Division 1 areas?
Yes, it is rated for Division 1, Group A hazardous locations. - What is the purpose of phase reverse?
It lets you choose which sensor state triggers an alarm output. - Is the output relay suitable for high loads?
It handles up to 0.5A at 200V DC or AC, but suppress reactive loads.
