DOUT over curent

Louis DUBARLE 3 weeks ago • updated 3 weeks ago • 2

Hi all, recently built a 24V power-supplied machine with 4 HS DOUTs driving solenoids. Swapped with 12V solenoids unintentionally, and now 2 are not responding. Also, one of them is providing 24V output without any command. Did anybody ran into this issue before ? There is not any protection to limit output current ?

You do have a over current threshold of 4200 mA for the DOUT HS outputs on the C4x family.


Are you using any external clamping diode on the solenoids?

Louis DUBARLE 3 weeks ago

Indeed, our solenoid connectors (HIRSCHMANN type connectors) do include a clamping diode.
