DESCRIPTION
The 420E2 series is a two stage transient voltage protector providing 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 420E2 series is designed to protect 4-20mA analog control loops from differential
and common mode transients. Terminals 1 and 2 are designed as the line pairs for
both the line and equipment side of the protector. A transient voltage suppressor is
internally connected across each line pair for differential mode protection. Each line
pair is referenced to ground.
This product can also be used on telephone, signal/data lines, security timing and
control interface circuits.
