232B - 232E

INDUSTRIAL COMPUTER DATA LINE PROTECTOR

DESCRIPTION

The 232B/E is a two stage transient voltage protector that provides primary and secondary protection against lightning,

inductive switching and electrostatic discharge (ESD) transient threats. The first 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 timing and control interface circuits.
