• All the active surge protection components are contained within the pluggable module, allowing quick removal without disconnecting the wiring. Replacement costs are reduced, too, as only the modular part needs to be changed
• The MTL SDM range offers the same slim-line 7mm footprint of that of the MTL SD range, increasing the packing density, resulting in saving both space and cost, which potentially reduces the number of cabinets needed
• An optional innovative ‘make before break’ design ensures uninterrupted signal and loop protection upon removal or replacement of the surge module during maintenance. The signal to DCS shows no interruption avoiding nuisance alarms
• A diagnostic LED option is available to provide a clear, visual indication of a failed module so that faults can be identified and rectified immediately
• Additional options include a Fuse to give extra protection against fault currents and a convenient disconnect method for isolating field circuitry without module removal.
• The MTL SDM is backwards compatible with the MTL SD range which means users can quickly and easily upgrade to the MTL SDM when next carrying out maintenance upgrades and take advantage of these great new features.
• Multi stage hybrid circuit
• 20kA maximum surge current 
• Voltage ratings to suit process I/O applications
• Intrinsically safe
• ATEX, IECEx and Class 1 Div1, Class 1 Div2 certified
• 10 year warranty
