422ELC

Only One Name Means ProTek’Tion™

DIGITAL PROCESS DATA LINE PROTECTOR

DESCRIPTION

The 422ELC is low capacitance, two-stage transient voltage protector that provides primary and secondary protec-

ꢀon 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 422ELC is designed to protect data lines from diﬀerenꢀal (line-line) and common-mode (line-to-ground) transients.

Terminals 1 & 2 and 3 & 4 for the 422ELC are designed as line pairs. A transient voltage suppressor is connected

across each line pair for diﬀerenꢀal mode protecꢀon. Each line pair is referenced to ground.

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. Capacitance

over the operaꢀng voltage range is important. If capacitance is nonlinear, distorꢀon, loss of data or access to the I/O

port can occur (See Figure 1).
