L-com Weatherproof Lightning Surge Protector for RS-422/RS-485 & 24VDC Power Lines

The HyperLink ALS-D25P24DW is designed to provide superior lightning and surge protection for RS-422/485 control and 24VDC power lines. These protectors incorporate individual protection circuits for the RS-422/485 control lines and DC power lines. All housed in one NEMA rated weatherproof enclosure. These units feature a weatherproof ABS enclosure with gasketed cover and concealed mounting holes. Water tight cable glands provide entry and exit points for cables. A ground clamp on the enclosure's exterior provides a tie point for earth ground.

A high power 3-stage design is used to provide protection for the RS-422/485 control line. The 3-stage design can handle higher-level transients than a protector that uses only diodes. The first stage is comprised of a differential gas discharge tube. Stage two is a pair of current limiting series resistors and the final stage is a low capacitance diode array. The RS-422/485 control line is connected to the protector via its screw terminal blocks. The terminal blocks are removable to ease wiring. The ALS-D25P24DW is designed to work with either 1 full duplex or 2 half duplex RS-422/485 lines.
