1800 Series Signal Dataline Protector
Bourns 1800 Series Signal Dataline Protectors designed protect sensitive electronic circuits components from damaging surge voltages currents. Their extremely fast response clamping voltages make them particularly suitable protection signal data lines associated with computer, data communication, instrumentation, broadcasting industrial controls. They used directly with standard interfaces RS-232, RS-422, RS-423, RS-485 with instrumentation loops. Model 1800 Series Signal Dataline Protectors fast, rugged capable protecting against fast rising voltage transients well severe current surges associated with lightning discharges. Method Operation Bourns 1800 Series heavy-duty, multi-staged protectors. solid-state section intercepts leading edge surge with subnanosecond response time. Within microseconds 3-pole common chambered Tube capable handling 200,000 ampere lightning currents operates crowbars surge ground. protector remains crowbar state until surge passed line voltages return safe levels, then automatically restores line normal operation. There need resetting breaker replacing fuse. Application Protectors generally placed each signal data line current loop. case daisy-chain configurations (such RS-485), protectors placed each node. 1820 models provide both line-to-ground line-to-line protection designed differential signals (such RS-422 RS-485) 4-20 current loops. 1810 models provide line-to-ground protection separate circuits designed ground referenced signals (such RS-232) where return wire grounded protector. 1811 1821 models provide same protection modes high frequency applications. Related Bourns Protectors outdoor applications with inch ports (such field-mounted 4-20 transmitters), please refer Bourns 1669 Series Protector. this application, mixed 1800 Series Protector controller 1669 Series Protector field recommended.
