Various companies have developed of the "shunt diode" safety barrier over the past forty years. This is a passive network device that uses zener diodes, resistors and fuses to safely divert excess electrical energy to ground and thus prevent sparking in or overheating of equipment in hazardous areas. Their key benefits are low cost and the ability to operate with data in analogue DC or high-speed digital forms.
Kentron offers intrinsic safety solutions using ranges of shunt diode safety barriers from a range of reputable manufacturers. Each manufacturer produces product to industry requirements of performance and safety, with reputations for quality and reliability.
