Intrinsic Safety Interface Units - Eaton MTL 5500 Series

The MTL5500 Series is the latest generation of MTL intrinsic safety isolators designed to meet the needs of the intrinsic safety (IS) interface market for application focussed projects, from single instrument loops to fully equipped cabinets. Incorporating advanced circuit design and innovative isolating transformer construction these isolators offer explosion protection and help protect electrical signals in hazardous areas ensuring a safe working environment.

DIN-rail mounting and plug-in signal and power connectors simplify installation and maintenance. These IS units are powered from a 20 to 35 V dc supply voltage, or, in some cases, from the signal itself.

The compact 16mm wide design reduces weight and gives a cost-effective high packing density and reduction in power consumption. A wide range of module options includes both single and multiple channel isolation barrier devices. They build on the success of the MTL5000 series to bring the benefits of galvanic isolators with exceptional design and reliability.,II (I) GD (Ex ia) IIC,IECEx, ATEX (Baseefa) FM, CSA

Eaton MTL Zener Barrier, 14mA, 10.5V - MTL5500 Series - MTL5511/RS

To optimise safety in hazardous areas, choose this zener barrier from Eaton's MTL range. It processes standard electrical signals of up to 14mA in intrinsic safety systems. Use it in single-loop instruments or fully-equipped enclosures to divert excess electrical energy to the ground to prevent sparking and overheating, which can lead to damage and injuries. The unit lets you control a safe-area load with a switch or proximity detector located in a hazardous area. A line-fault detect (LFD) facility picks up short circuits in the field.

Features & Benefits

• DIN rail mounting capability allows you to easily secure the module by simply clamping it onto the rail
• Wide operating temperature range from -20°C to +60°C for use in demanding environments
• Fully tested and approved for use in potentially explosive settings

What's the difference between a zener barrier and a galvanic isolator?

A zener barrier diverts excess energy to the ground through fuses and diodes. Galvanic isolators use relays, transformers and optoisolators to provide isolation between the circuits in dangerous and safe areas.
