#166649 - At both needed! Responding to: Lukas Valecky's previous message |
Lukas said:
Do you mean the diode in parallel with the relay coil in my schematic or the snubber at the output pins of the relay when switching inductive load? At both you need a snubber, when the load shows some relevant inductance! So, also connect a free wheeling diode across your door opener. See figure 2 of this link http://www.autec-gmbh.de/english/D...E_KDR8.pdf Kai |
