Signal Line Protector OBVXJ series
surge protective devices for control signal are applied to the surge protection ofcontrol signal and twisted data pair (RS232, RS422, RS485 etc.), which can prevent various dialing equipment from permanent damage or transient interruption arising from inductive overvoltage, over current and other transient surge voltage caused by surge and industrial noise, etc
OBVXJ is a protector with RS485 input and output connectors, able to hold up nominal discharge currents of 5kA for each line.
○ Protection for data lines and the digital or analogical equipments connected (computers, PLCs, discharge cells, etc.).
○ Wide variety of SPDs for different working voltages.
○ Both common and differential protection recommended for this type of lines.
○ Allows the connection of two pairs of lines with a very small size (0,75 DIN modules).
○ Pluggable modules for its easier substitution in case of failure without the need of disconnecting the wiring. When substituting the module the line suffers no interruptions.
○ Earthing implemented through a metallic sheet opposite to the fixing DIN rail.
○ In normal conditions stays inactive, without affecting the line working and without producing any leakage.
○ Low residual voltage in all the working voltages.
○ Very fast response.
○ Connection with screw pressure, which provides better lightning current withstanding capacity than usual telephone connectors.
