BNV 30 is the series of devices for discharing transient overvoltages induced in 4-20 mA networks, within the BNV range. In accordance with IEC 61643-21. DIN rail format.
- Suitable for the protection of instrumentation installed in 4-20 mA networks. By their nature, they are highly exposed to induced transient overvoltages (surges) associated with meteorological activity.
- 2-wire protection.
- For nominal voltage. Un : 24 V.
- The BNV range also provides models for the protection of signal types RS 232, PROFIBUS PA, Binary signals, KNX bus.
