DB-HS is the series of devices for discharging transient overvoltages induced in RS 232 networks. In accordance with IEC 61643-21. DB format.
• Suitable for the protection of instrumentation installed in RS 232 networks. By their nature, they are highly exposed to induced transient overvoltages (surges) associated with meteorological activity.
• Protection of 23+GND, 17+GND, 14+GND, 8+GND and 7+GND.
• The DB-HS range also provides models for the protection of signal types PROFIBUS PA.
