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

To ensure safety in hazardous areas, opt for this Eaton MTL zener barrier. It's an intrinsic safety isolator that diverts excess energy to the ground to prevent sparking and overheating. This reduces risks such as fire outbreaks and electric shocks that can damage valuable equipment and injure workers. The unit provides a fully-floating DC (direct current) supply to energise a conventional transmitter located in a hazardous area and repeats the current in another floating circuit to drive a safe-area load. You can use it on single-instrument loops or fully equipped cabinets.

• Operating temperature range from -20°C to +60°C makes this module robust and suitable for use in harsh ambient conditions
• Designed and tested for installation in explosive areas

Intrinsic safety lowers the risk of electrical damage and fatal incidents. This low-power technique channels excess electrical signals to minimise the chances of sparks and overheating that can cause fires and electrical shocks in the workplace.

Reverse bias feedback (electrical signals) causes a small leakage. A zener diode regulates it by establishing a breakdown or constant voltage to normalise the flow.
