Introduction

The 1840 Series Signal and Dataline Protectors are designed to protect sensitive electronic circuits and components from damaging surge voltages and currents. Their extremely fast response and low clamping voltages make them particularly suitable for the protection of sensitive signal and datalines associated with computer, data communication, instrumentation, broadcasting and industrial controls. They may be used directly with EIA standard interfaces RS - 232, RS - 422, RS - 423, RS - 485 and with 4·20 mA and 50 mA instrumentation loops. The Model 1840 Series Signal and Dataline Protectors are fast, rugged and capable of protecting against fast rising voltage transients as well as the severe current surges associated with lightning discharges, in each case up to rated limits.

Features

• Low peak clamping voltage even during severe current surges
• Ability to repeatedly protect against high surge currents up to rated limits
• Convenient mounting and grounding to any flat surface or to DIN - 1 (TS - 32) or DIN - 3 (TS - 35) rail
• Cable shields are passed through and may be either grounded or arc - protected to ground
• Vibration - resistant screw - type clamp terminals
• Flame - resistant epoxy - filled housing

Applications

• Protectors are generally placed at each end of a signal, dataline or current loop.
• In the case of daisy - chain configurations (such as RS - 485), protectors are placed at each node.
