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

Need to prevent dangerous electrical signals from reaching devices in a potentially explosive area? Use this relay from Eaton MTL. It enables switches or logic signals positioned in a safe area to control up to two IS (intrinsically safe) circuits in a hazardous place via relay contact. A wide operating temperature range of -20°C to +65°C makes this unit suitable for use in demanding industrial environments. It's designed for standard DIN rail mounting, so you can simply clip it in place for quick and simple installation, without the need for tools. Use this relay to safely test IS fire alarms and adjust the tone of IS sounders.

• Backwards compatibility with MTL5000 series for versatility
• LED indicators clearly show operating status for ease of use
• Low power dissipation of 1.1W at 24V for minimal energy loss
• Reliably fast response time of 25ms

This relay has a robust contact life expectancy of 20 million operations at the maximum IS load, making it a long-lasting choice.
