Connecting a holding brake with high current draw (> 1A) to the device
The switching of inductive direct current via relay produces strong currents and sparking. For interference
suppression we recommend integrated RC suppressor elements, for example by Evox RIFA, denomination:
PMR205AC6470M022 (RC element with 22
Ω
in series with 0.47 µF).
