PRODUCT DESCRIPTION

MTL7728- MTL7700 Series DIN-rail mounting safety 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 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.
