05053 Only One Name Means ProTek’Tion™ 420E212 - 420E260 dual 4-20ma CONTROl lOOP PROTECTOR 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. 420E F EaTuREs aPPliCaTiONs • • • • Security Alarm Systems Industrial Control and Monitoring Systems Remote Tech Site Station Process Control Loops • Compatible with IEC 61000-4-2 (ESD): Air - 15kV, Contact - 8kV • Compatible with IEC 61000-4-4 (EFT): 40A - 5/50ns • Compatible with IEC 61000-4-5 (Surge): 95A, 8/20µs, Level 4 (LineGnd) & 48A, Level 4 (Line-Line) • Designed for 4-20mA Current Loops • Automatic Reset - Does Not Interrupt Service • Permanent Two-Stage Line Pair Protection • Common Mode & Differential Mode Protection • Subnanosecond Response Time • Effective Against Lightning, Inductive Switching and ESD MEChaNiCal ChaRaCTERisTiCs • Approximate Weight: 50 grams • Flammability Rating UL 94V-0 05053.R5 2/11 Page 1 www.protekdevices.com 05053 Only One Name Means ProTek’Tion™ 420E212 - 420E260 TyPiCal dEviCE ChaRaCTERisTiCs MaXiMuM RaTiNGs @ 25°C unless Otherwise specified PaRaMETER Operating Line Current Transient Source Voltage Transient Current (8/20µs) - per Line Operating Temperature Storage Temperature syMBOl IO TA TSTG valuE 100 6 10 -55 to 100 -55 to 100 uNiTs mA kV kA °C °C ElECTRiCal ChaRaCTERisTiCs PER liNE @ 25°C unless Otherwise specified PaRT NuMBER MaXiMuM OPERaTiNG liNE vOlTaGE MaXiMuM lEaKaGE CuRRENT @ vOP id µa 5.0 5.0 5.0 5.0 5.0 5.0 MaXiMuM ClaMPiNG vOlTaGE (8/20µs) @ 2000a vC vOlTs 22 44 46 60 80 95 MaXiMuM CaPaCiTaNCE MaXiMuM liNE ThROuGhPuT REsisTaNCE R OhMs 12 12 12 12 12 12 vOP ±vOlTs 420E212 420E225 420E228 420E236 420E250 420E260 12.0 25.0 28.0 36.0 50.0 60.0 @ 0v, 1Mhz C pF 6000 3000 2800 1500 1200 1000 iNsTallaTiON iNsTRuCTiONs There are two (2) terminals on the liNE sidE and three (3) wires on the EQuiPMENT sidE of this surge protection device (SPD). 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.R5 2/11 Page 2 www.protekdevices.com 05053 Only One Name Means ProTek’Tion™ 420E212 - 420E260 PaCKaGE iNFORMaTiON OuTliNE diMENsiONs diM A B C D - MilliMETERs MiN 63.50 30.48 17.15 - iNChEs MiN 2.50 1.20 0.675 MaX 35.56 MaX 1.40 A B 1 C GND 2 LINE SIDE GND 2 1 D EQUIPMENT SIDE ORdERiNG iNFORMaTiON BasE PaRT NuMBER (xx = voltage) 420Exxx MaRKiNG Logo, Date Code, Terminal Designations and Part Number 05053.R5 2/11 Page 3 www.protekdevices.com 05053 Only One Name Means ProTek’Tion™ 420E212 - 420E260 PaCKaGE iNFORMaTiON 420lE OuTliNE diMENsiONs diM A B C D E F MilliMETERs MiN 82.22 - iNChEs MiN 3.235 - MaX 95.5 82.98 57.2 30.2 15.5 30.2 MaX 3.8 3.265 2.25 1.125 0.61 1.19 A B WARNING LINE GND 3 4 D 1 1 Adhesive Mylar Label Terminal Screw 2 4 3 EQUIPMENT GND 2 C Mounting Hole for #8 Screw Terminal Strip #6 Screws F E 05053.R5 2/11 Page 4 www.protekdevices.com 05053 Only One Name Means ProTek’Tion™ 420E212 - 420E260 COMPaNy iNFORMaTiON COMPaNy PROFilE ProTek Devices, based in Tempe, Arizona USA, is a manufacturer of Transient Voltage Suppression (TVS) products designed specifically for the protection of electronic systems from the effects of lightning, Electrostatic Discharge (ESD), Nuclear Electromagnetic Pulse (NEMP), inductive switching and EMI/RFI.
