AD-BS 1 ST, AD-BS 2 ST, AD-BS 3 ST
Description
The overvoltage protection elements AD-BS1 ST, AD-BS2 ST and AD-BS3 ST have been designed for the protection of low voltage signal lines (e.g. 0/4...20 mA, 0/2...10V etc.). The overvoltage pulses can be caused e.g. by lightning strikes, switching operations in the power grid, inductive interference or static discharges. A special L-type is also available, which has inductors instead of resistors as longitudinal current limitation. This allows the voltage drop at the longitudinal protection to be significantly reduced and the signal to be protected to be less loaded. Due to the plug-in module design, the overvoltage protection elements can be easily replaced after response or during revision. After the protective element has been removed, the signal path is interrupted. Thus, operation without a protective element is not possible.
Application
Protection of technology connected to low voltage signal lines against overvoltage surges.
