Edco PC642C-008LC 8V Surge Protector.

PC642C-008LC 8V Low Capacitance 2-Pair Data/Signal Line Protection.

The Emerson Edco PC642-008LC surge suppressor is a dual-pair (4-wire) data line protection module implementing three-stage hybrid technology. This module addresses overvoltage 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 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 PC642 card edge module is gold-plated, double-sided and is designed to mate with the PCB1B gold-plated female terminal connector. When snapped together, the data circuits "pass thru" the protector in a serial fashion from the four "Field Side" terminals to the four "Electronics Side" terminals.

Compatible with RS-422 and RS-485
