Operation

Transient Voltage Filters

R-D networks (Resistance-Diode) are applied to circuits where transient electrical voltages can cause a malfunction or damage in solid state controls or control systems (PLCs, CNCs, NCs, Solid State Counters, etc.). The RDSs are applied in parallel with DC (Direct Current) coils to absorb the transients generated when the coils are de-energized.
