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.
