Edco PC642 Series
Zone/Loop/Data
The Ed co PC642 Series surge suppressor is a two- pair pair (four wire) module
i mpl em ent i ng thre e- stage hybrid technology. This module add resses over- vo l tage
t ra n s ients with gas tub es and silicon ava la n che components. In addi t io n, sneak and
fault cu rrents are mitigated with reset table fuses (PTCs). The PTCs increase res i stance
several orders of magnitude when over-currents exceed safe levels. A normal state
resumes when over- cu rrents are removed. The ability to sel f- resto re in this manner
significantly increases suppressor performance and survivability.
The Edco PC642 card edge module is gold-plated, double sided and is designed to
mate with the the Edco PCB1B gold-plated female terminal connector (sold separately).
When snapped together, the data circuits “pass thru” the prote ctor in a serial fashion
f rom the four “Field Side” terminals to the four “Electro n ics Sid e” termi na ls .
Term i nals 1 or 10 of the PCB1B must be at tached to Buildi ng-Approved Grou nd per
Edco Technical Bulletin # 2015.
PCB!B-WKEY may be ord ered along with PC642 module by addi ng “-Kit” to the end
of the module part number (Example: PC642C-036LC-KIT).
