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.
