05060 Only One Name Means ProTek’Tion™ 232B - 232E INDUSTRIAL COMPUTER DATA LINE PROTECTOR DESCRIPTION The 232B/E is a two stage transient voltage protector that provides 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 232B/E is designed to protect two line pairs or 4 data lines from common-mode lightning or switching transients. the datalines are isolated to prevent near to far end cross talk problems. This product can also be used on data and transmission lines, security timing and control interface circuits. 232B 232E FEATURES • 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) • 4 Wire Line-Ground Protection • Designed for EIA Standard RS-232 Data Lines • Permanent Two Stage, 2 Line Pair or 4 Line Protector • Subnanosecond Response Time • Automatic Reset - Does Not Interrupt Service • Effective Against Lightning, Inductive Switching and ESD APPLICATIONS • • • • • RS-232 Transmission Lines Category 3 Systems Control & Monitoring Systems Analog Signal Transmissions Telemetry Outstations MEChANICAL ChARACTERISTICS • Approximate Weight: 28 grams (232B) & 142 grams (232E) • Flammability Rating UL 94V-0 05060.R4 12/10 Page 1 www.protekdevices.com 05060 Only One Name Means ProTek’Tion™ 232B - 232E TyPICAL DEvICE ChARACTERISTICS MAXIMUM RATINGS @ 25°C Unless Otherwise Specified PARAMETER Peak Operating Line Voltage Operating Line Current Transient Voltage Transient Current - 8/20µs waveform Operating Temperature Storage Temperature Response Time SyMBOL VOP IO TA TSTG - vALUE ±25 200 10 10 -55 to 100 -55 to 100
