Keystone Electronics 232

DESCRIPTION

The 232B/E is a two stage transient voltage protector that provides primary and secondary protecton against lightning, inductve switching and electrostatc discharge (ESD) transient threats. The frst stage diverts the transient current through the ground terminal return path and the second stage clamps the voltage to a safe level without interruption of service.
The 232B/E is designed to protect two line pairs or 4 data lines from common-mode lightning or switching transients. the datalines are isolated to prevent near to far end cross talk problems. This product can also be used on data and transmission lines, security tming and control interface circuits.
