Discrete IO is fed from local panels, distributed, 24V power supplies. Suppressed 24V small relays coils are OK , once solenoids and big contactor coils get involved, those are fed by another bulk supply that can be tolerant of &quot;dirty&quot; transients.&nbsp; &nbsp;&nbsp;</span></p><img src="https://community.element14.com/aggbug?PostID=28739&AppID=42&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/manufacturers/analog-devices/b/blog/posts/powering-your-drive-final-thoughtsMon, 03 Mar 2025 14:01:41 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f53130c4-625c-4919-ac13-782bba7c87fcsvanderwolf0<ol> <li>#PoweringYourDrive</li> <li>#VariableSpeedDrive</li> <li>#ControlPowerSupply</li> <li>#AnalogDevices</li> <li>#SurgeProtection</li> </ol><img src="https://community.element14.com/aggbug?PostID=28739&AppID=42&AppType=Weblog&ContentType=0" width="1" height="1">
