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. 05053.R2 7/02 1 www.protekdevices.com 420E212 thru 420E260 DEVICE CHARACTERISTICS MAXIMUM RATINGS @ 25C Unless Otherwise Specified VALUE UNITS 100 mA Operating Temperature -55C to 100C C Storage Temperature -55C to 100C C 6kV V 10kA per line A PARAMETER Operating Line Current Transient Source Voltage Transient Current (8/20s) ELECTRICAL CHARACTERISTICS @ 25C Ambient Temperature PROTEK PART NUMBER MAXIMUM OPERATING LINE VOLTAGE MAXIMUM LEAKAGE CURRENT MAXIMUM CAPACITANCE VOLTS @ VOP ID A MAXIMUM CLAMPING VOLTAGE (8/20s) @2,000A VC VOLTS VOP C pF OHMS 12.0 25.0 28.0 36.0 50.0 60.0 5.0 5.0 5.0 5.0 5.0 5.0 22 44 46 60 80 95 6000 3000 2800 1500 1200 1000 12 12 12 12 12 12 420E212 420E225 420E228 420E236 420E250 420E260 MAXIMUM LINE THRUPUT RESISTANCE @ 0 V, 1 MHz R 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 stranded 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 420E2 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/ receiver/controller, etc. The location of the protector should be as close to the equipment requiring protection. 420E2 CASE OUTLINE 1.40" MAX (35.56 mm) 2.50" MAX (63.5 mm) GND 1 1.20" MAX (30.48 mm) 2 1 GND 0.675" MAX (17.15 mm) 2 LINE SIDE EQUIPMENT SIDE COPYRIGHT (c) ProTek Devices 2001 SPECIFICATIONS: ProTek reserves the right to change the electrical and or mechanical characteristics described herein without notice (except JEDEC).
