Intrinsically Safe Zener Barriers

We are 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.

Our MTL products became a world leading range with its options of shunt diode safety barriers and its support role in the emergence of this new technology. The early MTL700 range established itself as an ‘industry standard’ with a reputation for quality and reliability. Please note that the MTL700 range has been terminated.

The ranges have evolved over the years but the latest MTL7700 range is unique in providing a broad range of benefits that the instrumentation engineer looks for in a modern barrier.

With the MTL7700, continuing the heritage, our commitment to zener barriers is confirmed for many years to come.
