MTL7728+ MTL7700 Series DIN-rail mounting safety barriers.
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.
