White Paper by LanTech: Nowadays Industrial Ethernet switches and Industrial Ethernet based devices are more suitable for their environments and applications; they are designed to meet the riggers of the task at hand which in some cases includes a harsh environment like Oil, Gas and Mining industry.
Some of the facilities that would utilize equipment that would fall into this application environment would be Oil Refineries, Oil Platforms and Petro-Chemical Plants these types of facilities would have a need to install Industrial Ethernet based switches and devices for process control and monitoring. These types of facilities require devices that are certified to meet the harsh environments they produce.

In August, exida approved the 2-wire, loop-powered SSX and 4-wire, line/mains-powered SST family of safety isolators and splitters for use in a Safety Instrumented System (SIS) up to SIL 3 where only the input circuit is part of the safety function. It is also approved for single use in an SIS up to SIL 2. These new approvals strengthen the usefulness of the SSX and SST and highlight the advantages of our FS Functional Safety Series, which also includes the STA Safety Trip Alarm and the SRM Safety Relay Module.
The Guardmaster® 440C-CR30 Software Configurable Safety Relay is flexible, cost-effective, and easy to use. This relay is ideal for applications requiring as many as nine dual-channel safety circuits and controlling as many as five output zones. You can configure this relay using the Connected Components Workbench™ software.
Factory sealed pushbutton, selector switch and pilot light stations offered by Automation Direct are designed to prevent the igniting of external hazardous atmospheres by the enclosed arcing devices. Factory sealed devices eliminate the need for external sealing.
