Check the documentation (s7-1200 system manual or easy book) for limitations on current and voltage. franckaay roy Hi everybody I wonder if there are S7-300 or S7-1200 which can supply 48VDC, with modules of extensions 127vdc tor inputs and outputs tor that can provide 48VDC. thank you for helping me urgently .Good day and good start all week.

Digital Input https://support.industry.siemens.com/cs/products/6es7321-1ch20-0aa0/sm321-16di-dc48-125v?pid=440150&mlfb=6ES7321-1CH20-0AA0&lc=en-WW Digital Output https://support.industry.siemens.com/cs/products/6es7322-1cf00-0aa0/sm322-8do-48-125v-dc-15a?pid=450318&mlfb=6ES7322-1CF00-0AA0&lc=en-WW I prefer standard 24V modules with relays (for parts commonality). BTW, instead of waiting for people to respond, the SEARCH box works really well.

Thank you in advance and good day .
