422E Product details

DESCRIPTION
The 422B/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 interrupton of service.
The 422B/E is designed to protect data lines from differental (line to line) and common mode (line to ground) transients. 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 differental mode protecton.
This product can also be used on telephone, signal/data lines, security, tming and control interface circuits. For most applicatons, 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 connecton.
