422B - 422E

Only One Name Means ProTek’Tion™

DATA PROCESS LINE PROTECTOR

DESCRIPTION

The 422B/E is a two stage transient voltage protector that provides primary and secondary protecꢀon against lightning,

inducꢀve switching and electrostaꢀc 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 interrupꢀon

of service.

The 422B/E is designed to protect data lines from diﬀerenꢀal (line to line) and common mode (line to ground) tran-

sients. Terminals 1 and 2, 3 and 4 for the 422E and pins 2 and 3, 4 and 5 for the 422B are designated as line pairs.

Each line pair is referenced to ground. A transient voltage suppressor is connected across each line pair for diﬀerenꢀal

mode protecꢀon.

This product can also be used on telephone, signal/data lines, security, ꢀming and control interface circuits. For most

applicaꢀons, the product should be located as close as possible to the equipment being protected. A low impedance

grounding system is important to maintain a low voltage clamp between the line-to-ground connecꢀon.
