Plug-in format

HS2XJ is the series of devices for discharging transient overvoltages induced in RS 485 networks.OBVXJ designed for protection of data, communication, mea-suring and control lines against surge effects.The protector with RS485 input and output connectors, able to hold up nominal discharge currents of 5kA for each line.
■Suitable for the protection of instrumentation installed in RS 485 networks. By their nature, they are highly exposed to induced transient overvoltages (surges) associated with meteorological activity.
■Protection of 1 or 2pairs of wires.
■For nominal voltage. Un : 12V,24V,48V.
■Low residual voltage in all the working voltages.
■Available with optional Din-rail mountable.
