The HGLN-D2 series of high performance 3-stage lightning protector provide superior protection of differential or balanced digital or analog lines from transients and surges. The units will protect two pairs of differential data or analog signal/control lines. For more complete surge protection of data lines, the use of two units is recommended, one at each end of the line. For outdoor applications, this protector can also be used in a weather resistant enclosure.  P/N: HGLN-D2-12
