Intrinsic Safety Zener Barriers
MTL is a pioneer in the development of the "shunt diode" safety barrier. 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.
MTL became a world leader with its ranges of shunt diode safety barriers and its support role in the emergence of this new technology.The early MTL700 Series soon established itself as an 'industry standard' with a reputation for quality and reliability.
The ranges have evolved over the years but the latest MTL7700 Series is unique in providing a broad range of benefits that the instrumentation engineer looks for in a modern barrier.
With the new MTL7700, and continuing support for our other ranges, MTL's commitment to zener barriers is confirmed for many years to come.
