Data/Signal Surge Protection, 2 Pair Data/Signal Protection, 20V
The STC-642 Series of surge suppressors are dual pair four-wire modules using three-stage hybrid technology. This module addresses over-voltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses PTCs. The PTCs increase resistance several orders of magnitude when over currents exceed safe levels. A normal state resumes when over currents are removed. The ability to self-restore in this manner significantly increases suppressor performance and survivability. The STC-642 card edge module are gold-plated, double sided and is designed to mate with the STC-642 gold-plated female terminal connector, STC0PCB1B sold separately. When snapped together, the data circuits passes through the protector in a serial fashion from four Field Side terminals to the four Electronics Side terminals. Terminals 1 or 10 of the PCB1B must be attached to building approved ground.
