05053 Only One Name Means ProTek’Tion™ DUAL 4-20mA CONTROL LOOP PROTECTOR 420E212 - 420E260 420E DESCRIPTION The 420E 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 420E series is.

05053 Only One Name Means ProTek’Tion™ DUAL 4-20mA CONTROL LOOP PROTECTOR 420E212 - 420E260 420E DESCRIPTION The 420E 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 420E series is designed to protect 4-20mA analog control loops from differential (line to line) and common mode (line to ground) transients. Terminals 1 and 2 are designated as line pairs for both the line and the 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.

The Ground lead is considered ground for both the input terminal and the equipment wire connections. For the best results, the ground wire should be connected to a low impedance ground or the green wire AC power ground. It is recommended that a #14 standard wire be used for this connection. Field (current) loops or incoming signal/data lines are to be cut or disconnected from the equipment to insert the SPD. The LINE SIDE terminals of the protector are to be connected to the field loop wires. The EQUIPMENT SIDE of the protector is connected to the equipment/controller, etc. The location of the protector should be as close to the equipment requiring protection. 05053.R6 9/12 Page 2 ISO 9001: 2015 CERTIFIED 05053 Only One Name Means ProTek’Tion™ PACKAGE INFORMATION OUTLINE DIMENSIONS MILLIMETERS DIM MIN MAX INCHES MIN MAX A - 35.56 - 1.40 B 63.50 2.50 C - 30.48 - 1.20 D - 17.15 - 0.675 A C LINE SIDE B 1 GND D 2 EQUIPMENT SIDE 420E212 - 420E260 GND 2 1 BASE PART NUMBER (xx = Voltage) 420Exxx ORDERING INFORMATION MARKING Logo, Date Code, Terminal Designations and Part Number 05053.R6 9/12 Page 3 ISO 9001: 2015 CERTIFIED 05053 Only One Name Means ProTek’Tion™ COMPANY INFORMATION 420E212 - 420E260 COMPANY PROFILE In business more than 25 years, ProTek Devices™ is a privately held semiconductor company.
