MTL5561/RS, Eaton 2 Channel Zener Barrier, Fire & Smoke Detector Interface, ATEX

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 2-Channel Intrinsic Safety Fire and Smoke Detector Interface, Analogue Output, 6 to 30V DC - MTL5500 Series - MTL5561

Use this essential fire safety interface from Eaton to protect your workplace. This loop-powered, 2-channel unit is designed for use with conventional fire and smoke detectors in hazardous areas. When a detector is triggered, this device protects electrical signals in the area. It features reverse input polarity protection, which preserves the integrity of the system if there's a fire. DIN-rail mounting and plug-in signal and power connectors mean it's easy to install and maintain.

• Galvanic isolators for exceptional reliability in hazardous conditions
• Compact (16mm wide) design reduces weight and power consumption, making it portable and efficient
• Multi-channel capabilities to suit systems and circuit design needs
• 'No-fail' earth-fault protection for increased safety

What precautions should I when installing this interface?

Before installing this isolator, it's essential to make sure that intrinsically safe and non-intrinsically safe wiring has been segregated, and that units have been installed to comply with national standards. You should carry out the installation process in accordance with all relevant safety standards, codes of practice and site regulations.
