Model 1840 DIN Rail Signal & Data Line Protectors

Bourns 1840 Model Signal and Dataline Protectors are high performance Surge Protection Devices (SPD) designed to protect sensitive electronic circuits and components from damaging surge voltages and currents. Features include low peak clamping voltage, ability to repeatedly protect against surge, convenient DIN-1 and DIN-3 rail mounting, and cable shields that may be either grounded or arc-protected to ground. The device's extremely fast response and low clamping voltages make the series well-suited for the protection of sensitive signal and datalines associated with computer, data communication, instrumentation, broadcasting and industrial controls. The devices may be used directly with EIA standard interfaces RS-232, RS-422, RS-423, RS-485 and with 4mA to 20mA and 50mA instrumentation loops. The Model 1840 Model Signal and Data line 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.
