The Test loop interface module (TLI) provides interface monitoring for the series connection of ProMod cassettes or other devices requiring an isolated output. When connected to the ProMod surge protection modules, a maximum of 25 modules may be wired in series to form a test loop that monitors and reports any depleted modules in the loop.
