Data/Signal Din Rail

The DRS Series is a din-rail mountable, single-pair surge suppression module implementing three-stage hybrid technology. This module addresses overvoltage transients with gas tubes and silicon avalanche components. In addition, sneak currents are mitigated with ressetable fuses (PTCs). The PTCs increase resistance several orders of magnitude when overcurrents exceed safe levels. A normal state resumes when overcurrents are removed. The ability to self-restore in this manner significantly increases suppressor performance and survivability.

The DRS Series mounts onto a standard 35mm industrial din rail. There are three "Field Side" and three "Electronics Side" screw terminals. One is reserved for a shield. Three electrically tied ground terminals are provided for grounding the DRS Series unit to Building Approved Ground. Shield is isolated from ground. For a 2-terminal version without a shield order the DRS-xxx-2.

** WARNING!! For Discrete Signal Use Only. Do not use DRS-130RMS on 120 VAC Power Lines. This unit is a Non-Hybrid, MOV design, rated above 5A operational current and can withstand greater than eight occurrences of a 10kA 8x20µs waveform, and greater than 1000 occurrences of a 200A 10x1000µs waveform.
