Can you use an SSR? 24 volt ouput signals, coil need slightly more than 1A, around 1.3A but driver is not strong enough. Chinese make PLC amplifier module for this purpose, they fit on DIN rail, really handy devices but take weeks to get. https://www.aliexpress.com/item/32801056562.html?spm=2114.search0302.3.90.54db1d60xhGYMS&ws_ab_test=searchweb0_0,searchweb201602_0,searchweb201603_0,ppcSwitch_0&algo_pvid=bc99d82b-1e53-4878-ae9f-f2c3f1d63393&algo_expid=bc99d82b-1e53-4878-ae9f-f2c3f1d63393-13 Sweden ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Output is 24V more or less standard for PLC or similar but the one above for connection to Micro Controller. I could simply use a transistor with a resistor on the base + a free wheel diode but a module is a better choice. ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Would expect the variant pulling to ground be slightly cheaper and better as if I remember NPN or N-MOS transistor is if I remember correctly is slightly cheap/better than the P variant, an extra transistor might also be needed. No big deal but it is slightly in wrong direction and usually work equally well pulling downwards.

Sold some wood, plenty of it here and the money is needed for these.
